paulsuerth, You are looking for the ABS speed sensor. The RR ABS speed sensor part number for '91 LS400 is 89545-50020. The speed sensor cost approx. $110-130 dollars, some dealers will charge over $200. Best to shop for OEM at one of the discounted Lexus dealerships. Use search to find them in the LS400/LS430 lexusownersclub forum.

All, Does any have an pictorial of an 1st Gen LS400 front wheel bearings removal and installation? I have a copy of the service manual pictures. I taken everything out of the steering knuckle except the bearings holder. I am planning to buy a shop press this week from Harbor Freight. Once I know the amount of pressure needed to press-out/press-in the wheel bearings. Thanks,

arsvivendi, I agree with VMF. Lexus issued a Technical Service Information Bulletin on ATF. The introduction of Automatic Transmission Fluid type T–IV makes type T–II obsolete.Use type T–IV for all applications that specify ATF type T–II. I would switch to Toyota transmission fluid type T-IV.

eagleski, You can purchase a OEM EGR valve from Park Place Lexus at $128.00.

Lexusing, As a precaution, please disconnect the negative battery cable before any work is done.

Oldschool, RockAuto.com has the valve cover gasket set (both right and left) by Beck/Arnley part #0361467 for $17.58 use this discount code: 112827122870 an get additional 5% discount on that order. The Lexus service manual will have a section on removal/installation of valve covers. Maybe someone will email you a copy.

seattlelexusguy, I would suggest you get a copy of the Lexus service manual. Maybe someone will send you a copy of the procedure with pictures. Here is a list of engine smoke anaylsis: Blue smoke indicates that engine oil is being burned, if the smoke is coming from the exhaust. If the smoke occurs during acceleration look at the piston rings as it source. If it occurs during deceleration look at the valve guides as it source. Black or very dark brown smoke is usually associated with an engine that is running rich. You might want to look at the fuel injection system. White smoke has two common sources, transmission fluid and/or antifreeze. Check the vacuum hose, usually located to the transmission output shaft housing. I am not for sure on the LS400, since I have not look. The service manual will be your best source. If you see transmission fluid in the hose, replace the vacuum modulator. If there is no tranmission fluid in the hose, then most likely source of the white smoke is a blown head gasket, a cracked cylinder head, or a cracked block. These conditions can be confirmed with a compression test or cylinder leakage test (Best). Another way to determine whether white smoke is burned tranmission fluid or burned antifreeze. The antifreeze has a distinct sweet odor, whereas the transmission fluid just smells smoky.

Thanks 99lsguy!

Thanks jzz30! I thought about the exact same thing, but I did not want to possible damage the nut. I did find a service metric wrench 15-piece set for $50 at overstock.com. Plus I purchase a thin beak jaw adjustable wrench and plastic jaw covers at Sears.

Here is a excellent web site for Lexus/Toyota service tools reference. They sell directly to the public. If you need know what tool number the Lexus/Toyota service manuals are referring to check out the site. Lexus/Toyota Special Service Tools

While as you know shocks and springs acted as one to check compression, check rebound and control the amount of road shock transmitted to the vehicle. A softer springing to improve riding created a need for better dampening of road shock. According to your signature you have H&R springs which has lower your OEM height and your compression and rebound of the shocks. You are going need a firmer shock to work the H&R spring or you are going to need to switch back to the OEM springs to work with the Tokicos shocks. The Tokicos shocks are slightly firmer than OEM shocks when used with the OEM springs.

For those of you who want more information from Lexus owners. http://www.planetsoarer.com/bushes/bushes.htm

wucantstop, Most of them were traded-in for a newer car, except for the MB S500 which I sold out right. My wife still can not believe I went out an purchase a used car. :) I have some many stories about each car, I could be here for days taking about them. I just got tried of buying new cars, if you can believe it, my wife doesn't. I still debating about even getting the new 2006 S500. I just don't feel the same about cars. I am only 37 years old. Working in the computer industry has been and still is very good to me. I better stop for now,

VMF, The VFT bushes are slightly stiffer than OEM from what I have read from SC and Soarer owners. I am not sure what the price will be. From Lextrem.com The VFT bushes are not like typical aftermarket Nylothane/Polyurathane hard durometer bushing kits, which, whilst being a cheaper option, will also ‘noticeably’ degrade a vehicle’s ride quality and comfort level. An increase in braking stability is also achieved with VFT control arm bushings as the control arms will not shift or oscillate forward and backward under the extreme lateral loads experienced during heavy braking. If other suspension upgrades such as springs struts or sway bars are installed the benefits of each will be maximized when used in conjunction with the VFT bushes.

Since the first LS400, Lexus has been changing there suspension to be firmer. I think the Euro-tuned LS430 is very positive step in grabbing even more BMW and Mercedes-Benz customers. If you really think about it has much different is each car no matter who manufactor the vehicle. The suspension in use today, all have one thing in common; they all use the same principles of geometry. The brakes are sliding caliper, floating caliper or fixed caliper using a different number of pistons to stop the vehicle. The key to me is who is the automobile company supplier! I can go on and on ...

Great news for us 1st Gen LS400 owners! For what I have read this bushings are very close to OEM. '90-94 VFT Bushings

Vyhanh from what you describe, it sounds like transmission pan. The rear differential sits between the two rear wheels. The transmission pan is know to leak if the gasket has not been replace on regular basic.

Vyhanh, I glad you were able to get the dam rotors off. I had the same problem but I used a rubber malet to get the rear rotors off.
