I've looked back over my records and it's actually four and half years but only 24k miles, so still premature, however, I'll try to keep this as short as I can but I need to add some context so apologies and here goes... When I bought this car in 2017, it wasn't as smooth as I was expecting but it had a very good MOT & service history. It didn't feel smooth at any speed and less so at higher speeds. I took the car to my usual mechanic and asked him to check the wheel bearings & he found nothing wrong. Over a 2 year period (along with MOTs and servicing) I had the following done, only one thing was done without sufficient reason:- Wheel Alignment - Was pulling to left before & after the alignment and they couldn't/didn't align the rear but no smoother. (Didn't go there again.) New Tyres - Worn tyres but no change to the ride. Alloys Refurbished - Tyre fitters mentioned rims were a bit grubby and I may get air leaks but they held their pressure very well. New Lower Control Arm Bushes - Progress. Did this after reading this site. This removed a vibration at motorway speeds but all speeds were still not smooth. Engine & Transmission Mounts - I admit this was the only thing I did for which I convinced myself out of desperation. No change. Rear Discs - Wear and tear. After two years, my not very smooth ride was now starting to get worse & noisier. I took the car to Lexus who diagnosed a worn NSF wheel bearing. I was gobsmacked when I picked up the car because I now had the smooth ride I was expecting. Soon after, I also had the OSF wheel bearing changed. About a month after having the OSF wheel bearing changed, I hit a massive pot-hole on the off side. One tyre was damaged but I thought all was OK. However, very soon I felt the smooth ride had deteriorated. (Paranoia?) The necessary new tyres following the pot-hole damage (and they were close to worn), and a few months later, having the wheels road force balanced, didn't change things. I felt like I was back to square one. The following was done with no change to the ride:- New NSF Track Rod End - MOT failure Wheel Alignment - Front & back now fully aligned including the ride height. That's an equally long story and a relatively cheap fix (but not if Lexus had had their way), if anybody is interested. New Tyres (2 years later) - Wear & tear. Over the last year or so, I was now getting a speed related whining sound from the NSR corner. It didn't get picked up in two MOTs or servicing. I kept meaning to take it in but I wasn't travelling as much & I kept putting it off. Anyway, I eventually took it to my usual mechanic and said I think I had two problems; a not very smooth ride at the front and a whining sound from the back. He diagnosed a clearly worn NSR wheel bearing and said the OSR was just starting to go. He suggested we change these first and see where we stand with the ride. Noise has gone but I'm still left with the not so smooth ride. So I've been back to my mechanic and he's compared wheel bearing noise with a stethoscope and says the OSF is noisier than the NSF so hence the reason the change this wheel bearing.

Yes, that's how I read it initially (EUR or HONG KONG...). Which raises the question, what does it mean here?

Thanks for the responses and apologies for not responding sooner. My VIN calls up 43550-50031 & 43550-50011 but what is the significance of "EUR HONG KONG OR SINGAPORE OR TAIWAN SPEC" alongside the 50011 part? I had both front bearings replaced by Lexus a couple of years back and they fitted 43550-50032. (I think somebody may be thinking why I'm looking to replace a front bearing again.) Andy

Hi, I'm looking to order a RH front wheel bearing for a UK LS430 2004 from Amayama. Looking at various EPC catalogues (7ZAP, LEXUS-EUROPE, PARTSOUQ & AMAYAMA). There are upto three numbers which come up (or two if I enter the VIN). I think I know which number I would go for but for one thing which is puzzling me (which I'll reveal later). I'd be very interested to know which number you would select. Regards Andy

Sorry, forgot to say, this is for the 2003- 2006 models. Andy

I've attached height information for the LS430. Hope this helps. Andy M_25_0004.pdf M_26_0008.pdf

Hi Foulsbane, There is only one speaker on the rear shelf, the sub-woofer. Please see the attached file. Regards Andy Audio Components.pdf

I thought the same about mine. Sound was distorted but the foam appeared all OK. But the foam had detached from the outer rim which was not immediately obvious when I first looked so worth checking. Regards Andy

Having read posts on this thread (and on https://www.lexusownersclub.co.uk/forum/topic/115512-ls430-build-thread/) I had my lower control arm bushes changed last year.(I've only just recently starting posting on this forum having meant to have started sooner after buying an LS430 18 months ago.) I was experiencing a low frequency vibration at speeds from 60mph+. It felt as if my trouser legs were flapping about! Changing the LCA bushes fixed the problem. So a thanks to John and Peter for their respective threads. The pictures below show the state of the bushes (2004 LS at 115,000 miles). Regards Andy

I would strongly recommend you buy a replacement from Toyota. I spent hours looking for a replacement online but battery capacity, size and even terminal location wasn't consistent between suggested replacements. I contacted Toyota and was surprised to find the price was cheaper than any of the so called alternatives. This was about 14 month ago and I recalled seeing this same recommendation on this forum. Regards Andy

The attached diagram does appear to support what you say, i.e. "the left 1/3rd of the display must mean the leftmost 2 sensors". Regards Andy Sensor_Location_M_67_3.pdf

Are you able to measure the sensor you removed (or possibly also the new sensor)? (Ref attachment, 2nd page). Regards Andy PS I'm new here. F_L_Sensor_M_05_2240.pdf
