Come to think of it: drivers side with click click noise rotated freely. Passenger side where I thought issue is: sounds like brakes rubbing and does not spin so freely but maybe not brakes...

At last now the weather is with us I jacked the car up. Neither wheel had any play, however the drivers side had a regular click when I spun the wheel. I was sure the vibration noise was passenger side but I suppose it might just seem that way... Nothing is catching and brakes are recent and in good shape. Surely has to be the bearing? Completed an oil change too so that’s for another year.

Most manufacturers’ franchises run a fuel system cleaner through on a mid to full service. Lexus sell a fuel additive. I put Redex in about once a year to clean the system and injectors. I’ve used a catalyst cleaner after a failed mot for idle gas levels...fixed with no further issues since. Very likely it cleaned up the O2 sensors too etc. A premium fuel would probably afford the same benefits?

If safe to do so...run with the auto air on system off for a short time. The needle will soon point to a warming engine...then all can be switched to auto... Fastest way to warm up engine.

Hi I had same: Lexus Parts Direct (Fish Brothers) https://lexuspartsdirect.co.uk/trade-homepage/ will sell a discounted Y section genuine part. Then you need to get it fitted. My ATS were prepared to do this but I opted another route. or... Call Grove Garage 01273508606 they are in Brighton - they can fabricate or repair the y section and fit: they did mine and many other forum members too. Ex Lexus and are very reasonable price wise.

£15 That’s a lot for a battery change...I buy known brand from wherever I can get it. Change it when you can’t remember doing it last. My LS400 fob is a tiny bit fiddly in that it needs a tiny driver and a mixture of firm delicacy. £40 for a watch battery...🤔and not diy able. That’s anti EU... yep we signed that before the end and it stands.

Hi Malc Yes they have their magic! Mine is an old 1995 Sport with a chain driven 1.8 - had the head-gasket done a few years back. It's an LHD and sits in a garage in Spain for most of the year. Now a classic, it feels a bit long in the tooth but it goes very well, has aircon, and we've done a lot of mileage in it. Wife is Spanish so we have roots there. Handy when fixing the car. 🙂 Parts are expensive - labour cheap. Before Brexit I shipped parts from the UK. I'm not going to get the needed 3/4 exhaust system into hand luggage...🧐 Simon

Hi I’m wondering about the wheel bearing. My fridge freezer motor is in the process of packing up...please bear with me...😉 Now I can hear the high end damage of the bearing motor-but it is also creating a low bass droan too. Tyres are Continental 16” diameter...balanced a while ago...I’d expect feedback through the steering wheel yet all is good. Same with flat spots...I’ve had those funnily enough on my Alfa 155. I can’t get it up on a jack until the weekend.

Ahh quite right on the value. Classics World comment: "As a modern classic, the LS400 may lack the visual appeal of a Jaguar but their legendary reliability makes them a very practical proposition." Jags are works of art. The LS400 won't make the value for an investment. If Jags had Lexus build quality - and were as easy to work on...I'd be Jag. 😊

Hi I'm nearly up to date with proactive maintenance although I admit I need front upper carrier arms. Last job was rear discs and pads that are now bedded in. Next job will be annual oil & filter change: Lexus oil is now priced more competitively than the Euro brigade so i'll be on the Lexus Parts Direct site. Problem: - Cold morning I noticed for the first time a bass level drone resonating from the front end. - Now seems ever present although sometimes more noticeable than at others. - Not tyre noise as I can hear that distinctly and vary over different surfaces. No out of balance symptoms. - Speed range 40 - 60 mph. - It's not engine related as engine speed does not effect it. - Breaking does not seem to change it either. - I get a general slight/low level of vibration - but not through the steering. - Tyres are up to pressure with 4MM+ tread - a bit more fronts wear outer edge but I've had worse. - Once I had the sensation it was front of vehicle passenger side. It's nothing obvious and unlike me, although I will fret on it, I'm inclined to leave it until the issue clearly identifies itself if it doesn't drive me mad first. Any ideas..? 🤪

It’s all very confusing and like the vaccine assessment turning around. Lots of “experts” about. Self-proclaimed scientists. Most oils are excellent quality. Use as recommended...why use an additive to compensate for engine wear? Maybe the engine needs some maintenance. All accounts state fully synthetic is superior to conventional oils. How on earth does a liquid stick to moving parts over static...please 🧐 oh yes we have a specialist who can blind with science. Cars don’t like being left...even over a really cold weekend. It’s not just the engine waking up...it’s the pressure in the hydraulics, fuel system...noisy injection tapping out like a knackered engine, the VTI waking up too. Not to mention the suspension, drive train...and us-the driver. Oh and the pulleys the wheels and belts. Bah humbug. 😉

I had a couple of BMW 635 coupes of the ‘80s which were very nice. But head gasket, rust, rear swing out under hard cornering, tyre grip from cold (limited metric choice) awful. Passenger in the old 3M series lhd this is a racing classic with amazing grip on a wet road... Owned a modern one but average. Jags...done them they are expensive scrap. Lovely designs. Best was 95 XJ 4ltr. currently looking after my eldest son’s 2007 clk 350. Nice car. Just after the appalling engine failures...yet solenoid magnets x4 need replacing as per usual...not expensive at 30quid each but please what of quality control? He’s peeved as it’s “slower” than my 2000 Lexus 400 🤭😁🔧

For the Mk4 LS 400: 1999 Lexus LS 400 0-60 mph 6.2 Quarter mile 14.6 🤫

Take it from a few of us on the Forum...check the dealer price and take your motor there...if they are decent they will swop it over for you too. Job done and OEM.

Hybrid version?

The red light does flash permanently so that’s fine. Lexus are not known for draining batteries as a rule where components fail to shut down and cause the dreaded drain. A light won’t pull that much juice if left on but a faulty earth would. I’m not trusting the battery so checking that is the first step. Then the alternator.

Indicator fixed...sort of... I was having problems securing my passenger side indicator unit: it would fly out and either hang of flap about at speed. It just gave up fitting whatever I wedged, stuck or wired to keep in still. I bought a replacement unit and noted the old one had two missing lugs to the outer side and the bracket loop on the headlight unit had broken off. With that the stress on the top bracket was too much and it gave up. With help (again) from Andy the partsmeister from Lexus Reading I got hold of a bottom grommet that fixes the...anyway I think the pictures will explain. I've got a better fit but it does look as though previous wing damage has changed the wing enough to distort. So now it's not perfect but serviceable. Velcro is retained to attempt some hold where the headlight fixing should be - I'm not getting a new headlight unit! I'll be interested to know whether there ought to be another grommet or lug in the top hole...couldn't find one listed and I'll leave the other unit well alone so I'm not checking there!

Yes Cat C is very annoying but it appears to be insurable and that's worth checking out...in any event I'd expect it to lower the asking price. If you haven't driven a Mk4 before...it's a blast...and very fast... I think most 400's are project cars in some respect...at this age there is always something? Here's my revised list: -Upper front suspension arms -Engine undertray replacement -Radiator cowl replacement -Renovate wheels -Repair ding/misshapen front wing -Repair dent and leading edge damage to rear wing -Repair dent to rear bumber -Respray or replace front bumper + lights

My front sensor was Pagid P8656 from Eurocarparts at a stiff £45 but I baulked at the cheap ones although I think they might’ve been fine. The rear one could be re-used as although some wear was evident it wasn’t enough to bear the contact. If you have time, Rockauto in the States might be a good source.

On the Mk4 the sensor sits at the bottom of the pad...in the fork of its body: that’s on an original pad. There is indeed a recess at the front pads and it is different to rear. A small clip secures the sensors in place. the fork end is bottom/solid end with hole is top: these are OE in the pic.

It’s one per pair...should see the electrical socket and they are both (front and back) on the driver’s side. Fitted to the bottom of the pad at the rear. Can’t recall front 🤭

😂 I’ve seen both 2 and 3 year Lexus warranty: 5 years for hybrid batteries. My Lexus unit is over 5 years old now...🤞

I tell you what...if it’s taken me a bit to get back at fixing things under the bonnet...I might wait a bit for an operation or an airline flight. My MOT advised that my rear LS 400 pads were getting a bit thin. Following a horrid job replacing the fan bracket largely due to my rustiness and not wanting to strip down the engine front...I worried the brake job would be more of the same. A quick prayer to Saint Eligius with apologies if he only covered unionised or professional mechanics...I pulled out my toolkit. I managed to get discs and pads for £202 from Lexus Parts direct. I didn’t mess about with the carrier 17mm bolts undone with my medium torque wrench and hammer and spanner on the carrier. Big joy was that the whole assembly looked freshly or recently serviced...not bad for goodness how many years. 🤭 The disc retaining screws looked new and came out a treat. The discs came off without drama...I cleaned everything with a brake cleaner and non contact areas with a wire brush. The parking shoes looked in very good order. (You were right Steve). No point touching those. I used specific brake grease and only used copper grease for bolts and general contact areas. My trusty caliper compression tool made the caliper work simple. (I recommend as you can use on most vehicles and well worth having one). On completion everything was torqued up. The brake fluid returned to the max level in the reservoir and...without adjustment...the parking brake only needs 3 clicks. So thanks to St Eligius.

Well there’s no way you can’t get or repair this...a matter of finding the solution provider...

I'd try Lexus to see what they have and Lexus parts direct might do you a cut price... Other options are breakers... Or they'll be an aircon magician who will fabricate a new one probably using the brackets from the old pipe. I bet that will be cheaper than a new bit. US would be my get out of jail card. 🧐
