#691 of 2081 1992 LS 400 differential bushes
May 05, 2002 (10:32 am)
I have a 92 LS400 with 154,000 miles.
Last time car was serviced by Lexus, they reported that the differential bushes were split and should be replaced. I opted not to replace them.
A few months down the line, and the handling has got really sloppy, especially from the rear. A lot of the time, changing lanes at higher speeds (40+ mph), you get kickback which I have never felt before on the car.
Any ideas? Does anyone know what a differential bush does?
Thanks in advance,
P.S Lexus were ranked No.1 in UK dealer survey and No.1 in reliability survey last week.

The differential weather boots crack and allow water into the shafts.
Generally the shocks [dampers in UK] are worn by 100k or sooner also the rubber bushings in the upper/ lower suspension arms require replacement around your mileage as do the front tension arms.
Hopefully you've had the power steering pump cleaned of wear debris....fluid flush to protect against hose failure taking out the pump, alternator, and steering rack.
#693 of 2081 another problem

Thanks Q45. So, it's probably a good thing to get the differential bushes changed then?
Now, I've got a new problem. The car starts strangely from cold (it's probably a misfire on ignition), but after 2 or 3 minutes the car runs normally. The dealer has checked it all out and says that nothing appears to be wrong.
He says the only way to test it is to try new plugs, new HT leads etc.
Has anyone come across this before?

Since your car has two distributers [4 cylinders each] and plug wires: rotors, caps, wires , sometimes coils but rare].
Cleaning of the throttle body and plate, EGR, just the normal maintenance of any engine you want to behave like new!

anybody else experience what i call "the tea kettle syndrome" with their LS? when at highway speeds, the inside of the car sounds like a tea kettle going off squealing and all. so i usually just turn up the music so i don't hear it. i was going to ask the dealer if it was some kind of seal wearing down or what. kinda sounds like it's coming from the front windshield at the corners. guess i'll ask when i go back again.
#696 of 2081 LS400 LCD clock display-black
May 08, 2002 (9:36 am)
I have a 1991 LS400 and the Clock/Temp display is starting to black out from the right to the left, I can still read the Temp. Lexus want $70 Labor and $645 for the new display. This price is not practical for a clock. Any options???

There are several previous posts for the LCD issue. You can replace it yourself and buy a refurbished part (~$200). For the price your dealer is charging for labor, I would have them replace it after you buy it.

The hourly labor prices [are kept low because they] include the markup on parts to arrive a real hourly margin.....say the average hour is 60% parts/40% labor so a $645 part might include a $322 margin [less the cost of inventory ordering/ holding, space, parts manager and helper salaries].
Most dealers won't install your parts since they are losing money on the techs time plus there are the warranty issues.
As an independent shop [which pays the dealer for parts....we get 30% off of LIST due to our volume]. We add $22 per hour for lost revenue to our $68/hr [$90/hr] when customer supplies parts and provide no warranty.
This is probably a win win if the customer can find the part used or rebuilt on the INET....except if the part fails the customer must pay to remove, ship it back, deal with where they bought it from, and then pay to have the replacement reinstalled!
Obviously the more the labor time the more the risk......think carefully when the replacement takes 3 hours or over on an externally acquired part supplied by you.

#700 of 2081 how to remove center console
May 14, 2002 (10:11 am)
I have a 1990 LS400 that has a couple of the lights out in the center console. The temperature control/clock light is out as well as the light which shows what gear you are in. I've heard that it is easy to fix/remove, but I don't know how. Please let me know how, thanks.
