You have a number of choices.

1.Have the seals replaced using seal kit.

2.have your the pump re coned (involves sending your pump off to have work carried out as no cores are in stock).

3.Purchase a remanufactured one from the USA.

4.Purchase pump from Lexus cost approx £450.00-£500.00.You could go gold and get a 15% discount.

5.Purchase a pump from a breakers and have it re coned.

I think you will find it is a good two to three hours to fit.

It all depends what you want to spend and how long you intend to keep car.I think it is about £150.00 to have pump re-coned.Replacing the seals is a tricky job.

Hi Chris,

I just fixed the Power Steering fluid leak problem yesterday on my 1993 LS400. The fluid has been seeping out for a while and finally had a chance to take a look at the source of the leak. I found that little rubber "O-ring" on the short pipe under the reservoir that fits into the pump was hard and brittle. The local dealer does not sell the o-ring by its self. The little rubber o-ring is part of the Pump rebuild kit with the price of $36. I found the generic rubber o-ring from the local hardware store in the plumbing section for $0.25 plus tax. I am not sure if this is a automobile quality o-ring or not. But, decided to try it out to see how long it will last. Even if I have to do it again, the replacement effort was not too bad.

It may not be strong enough for the heat and the chemical reaction from the fluid.

Are you sure that the fluid is getting past the pump spindle??

I have repaired two LS400's a 92 & 93 in the past where both looked like the seals had gone, in fact it was a 2p 'O' ring that goes on the spigot of the removable fluid container that sits on top of the pump.

On both occasions they had gone hard and flattened off, when replaced no more leaks.

Make sure it is the pump before you buy one they are an arm and a leg, and you won't know if it wasn't because it will obviously come with a new 'O' ring in it.

Hopes this helps you with a cheap fix.

Hi chris we have the same problem with our ls400 1993 and was wondering how easy it is to remove the reseviour and replace this O ring.. is the reseviour a push fit into the pump or is it bolted somewhere. any help appreciated.

thanks mal

Hi Mal,

This is a straightforward job, it involves quite a bit of removal of covers etc to get to the pump and reservoir but once you are there it does NOT require removal of the pump or the disconnection of any pipes etc.

Drain the fluid from the reservoir cup, undo the fixing that holds the cup in place if I remember correctly its a 10mm, then lift the cup away from the pump, use an old mirror if visibilty restricted.

The 'O' ring that needs replacing is quite obvious and fitted onto the cup spigot, try to locate a hydraulic specialist nearby and purchase the replacement 'O' ring from them (you will get a better quality one in the right size).

Reassembly is the reverse.

Best of luck its well worth the effort.

Hi Chris, Here is what I have found, website: discounttoyotaparts.com, sells the seal kits for around $23 US. They ship world wide.

I have replaced the "O" ring between the resouvior and the pump a coulpe of times with standard "O" rings and they just do not last and I believe I have leaks elsewhere. So I am going to order the complete seal kit and do the whole thing.

The Leaking fluid will eventually foul up your aternator and eventually can foul up your Crankshaft position sensor which will prevent spark ignition to the engine.

The LS400 is a fantastic car intil you develope a problem, due to all the sensors and precision components it can become frustrating locating the problem.

Since I have 3 of them, It is well worth my while learning as much as I can and repairing what I can on the cars.

I will post after I rebuild my power steering pump details of the project.

Best of luck: Bob

Hi all,

Reckon I have the exact same problem. I've just spent the afternoon (and £10 on sprayable Gunk) cleaning the pump, pipes, reservoir etc.,

to see if I can work out where the leak is coming from. It's leaking just in front of the driver's side (UK) front wheel, so can't be the steering rack.

Problem is, if I remove the reservoir to get to the O-ring, then I'm no longer mobile to get a replacement O-ring.

Anyone able to tell me what type of O-ring I need ? Not sure how you spec an O-ring, but I guess I need the inner & outer diameters.

Thanks in advance for any help

Justin

check the power steering cooler pipe just below the horns in front of the radiator,

its very exposed to the weather so tends to rust badly mine had pin holes in it so I cut a small section out and solved the leak but next time im going to change it to copper micro-bore pipe same stuff the use on household central heating,

easy way to get to it is remove the under shield on the front below the bumper

Worked out exactly where the leak is coming from.

It's leaking from the PAS feed hose to the rack. There's a bracket that bolts to the sump, and suspends the hose.

Fluid is collecting there (the lowest point of the PAS circuit). It's running down the hose from the rack,

so either the rack is leaking fluid down the hose, or it's the hose itself that is leaking. It can't be the pump,

because the hose between the pump and the bracket that suspends the hose is clean.

Lexus want £150.90 plus VAT for a replacement hose.

I'd welcome any advice on seeking a cheaper source

TIA

My 1993 LS400 also needed the little o ring. Changed the o ring and also put a little bit of black silicone sealent(In between the circ clip and plug) to help in stopping any leaks every coming back.

I have just carried out this replacement - thanks for the suggestion. Lexus main dealer wanted £129+VAT for 1.5 metres of bent steel tube :o so I bought 10 metres of copper microbore from Wickes DIY for £15 and a couple of end connector sleves (to cut down and solder on to give the rubber pipe some grip).

The whole job took about 2 hours including buying, bending, soldering and fitting the copper replacement.

Attached find some pictures:

Headlamp removed to gain access to the upper pipes - these were easier to remove than the ends connected to the cooler.

Remove spring clips and slide off rubber hoses from these:

This was the piece of tubing, bent to a similar shape to the original (large curve at end was to prevent tube kinking)

Small sleeve of copper soldered near end to provide grip for rubber hose:

Fitted back into the clamps:

And installed in the car:

No leaks and appears to work fine
