Hey Bob, First of all thanks for your valuable insight. Can you please explain what to look for in axle shaft to confirm anomaly. I mean some sort of indication to pay attention when I completely remove half shaft from car and disassemble. Matter fact, I received black moly grease with each boot I have ordered. I am going to use the same one. Moreover! I am looking for removal instruction for axle. Thanks!

Hi there, The other day I was under my 91 LS inspecting frame rust and noticed off white type semi solid fluid accumulated in a spinning fashion over axle shaft boots, under the body. I checked boots and there wasn't any cracks, so assumed grease is leaking from joints. I have no issue like clicking or grinding noise other than car vibrates at 70mph on the clock. I believe that is due to my tire and alignment issue. which is due in near future though. Chime in if you think axle shaft could be culprit for vibration at higher speed. Since, I didn't find any issue with axles operations, I decide to repack axles with new boots. I received boots with grease pack with it and want to know the procedure to remove axle shaft from the LS. I searched everywhere and on this forum, but there is no detail about it. I checked on TIS website but couldn't find anything more then schematics of differential assembly. I would appreciate if someone sheds some light on this grey area of maintenance. Thanks in advance...

Perfect!, Agree with that. I just want to make sure change bushing vs whole component difference. We are on same page. Thanks a lot. will surely check Amazon to save money.

Hi Billy, Thanks for suggestion on timing belt component kit. Sorry! for the confusion on the valve clearance due milestone. It is due @ 72 months and not @ 72000 miles. You are right it indeed sound like news due to my quick sight to maintenance schedule. It is 72 months. You have experienced 12 great LS and your suggestion would be worth to have. Could you please shed some light on other parts selection. I mean to say, spark plug wires, steering and suspension components,etc.? Steve suggest to replace bushing if it is required rather then whole component but I believe from my personal experience that metal component has also tensile strength, which gets degraded by use under constant stress (Becomes little too flexible). I learn it when I replaced control arm and installed quick struts to my Camry. The car feels more rigid and confident. Which wasn't a case previously when I did only bushing and struts replacement. I may be wrong and it is total different machine.

Thanks! Landar, I knew, I will have good amount of clues on how to troubleshoot issues with my lex from experts. I will check as you suggested and update information here as I get along with troublemaker.

Thanks! Steve for taking your time. Ever since I have posted for suggestions I am counting viewers but at-last you broke that sequence . Today I went for wheel balancing and ask for check the tires and any potential issue relevant to symptoms. He confirms that wheels are good and balanced but he has seen, this kind of problem, due to worn struts. Also somewhere in the other thread it turns out to be drive shaft weight balance problem. I checked struts by pressing with my body weight to front and rear and there is no bouncing effect. what could be possibly wrong with struts? Any suggestions. Moreover, I will check drive shaft this weekend and see if I can found any balance weight flew off. Chime in, if there is another way to check struts to confirm the culprit. It would be much helpful towards my diagnostic process . I am gonna change water pump and seals as well + just came across owners manual and in that, it is suggested to check valve clearance every 72000 miles. this one has 172000 so will do that also along with spark plugs.

Hello from Newbie to all Lexus owners and Gurus, I am recent owner of 1991 Lexus LS400. It has 172000 miles on it. I am new to Lexus but long time DIYer of my other car and motorcycle. All I am trying to get advice from you guys and possible suggestions on repair. My questions are as below. 1. Car runs smooth, However drive becomes shaky after speedometer reads over 60. Please suggest where to look for. Nothing has changed in steering suspension by previous one and only owner. Engine oil changed before 6 month, Transmission/ deferential oil no record. Same for spark plugs too. I wonder timing belt lasted this long without changing it. 2. Are aftermarket parts from like rock auto and all works good? Trying be easy on my pocket and don't want to pay ridiculous price, but if there is no way then . Please Advice. I am thinking about giving good tune up; Timing belt with timing components, Spark Plugs with wires, rotors and distributor caps, thermostat and coolant flush, engine, transmission and differential oil, fuel filter, air filter, etc. Am I missing something OR over doing anything please Advice. Moreover, should I replace struts, control arm, tie rod (Inner/ Outer), Ball joint? What is ideal replacement milestone for all these? If it were my Camry, I wouldn't let it pass 100000 without it. I love this car and feeling sad that it hasn't had chance to get recharged. Thanks in advance.
