can someone pls help me. i had my water pump replaced by lexus. What parts were removed to replace the water pump? Since getting the car back, my car vibrates in drive and when I hit the accelerator, especially between 60- 65 mph and at high speeds...but only when I use the accelerator. Before replacing the water pump, the car was very quiet during idling, but I did experience the vibrations ablve before replacing the water pump...


Lexus told me to replace the transmission mount....I did that ...the vibration still exist...I cannot afford to keep experimenting with different guest fixes..., too expensive.....next lexus suggested that I replace the 2 front motor mounts.

Pls some one help me. What should I do? There's nothing with the mich harmony tires...already had them checked, and re-balanced...nice and round.

Any feedback would be greatly appreciated.

Thanks,

Gwen

 

Have someone put the car on a lift and inspect the tranny mount to make sure they actually put a new one in there. That is supposed to stop the vibration. From what I understand you shouldn't have to change your engine mounts, have them inspected first. The mounts are liquid filled. I've never had mine changed, but always inspected and they're still good with 244100k on the clock, still riding smooth.

 

Gwen,
Are you still having the problem? If so, two thoughts. 1) Mounts are easy to check. For the motor mounts, put car in park have someone push gas pedal in quickly while you observe engine. If motor mount is bad, engine will rotate in same direction as serpitine belt is turning. Normally the engine should move only slightly if at all. If that checks out ok, I would suspect the water pump installation. If they removed the timing belt to get to the water pump and installed it such that one of the overhead cams were off one tooth on the belt would see rough acceleration because the timing would be off just enough to run rough but at idle would appear to be ok. Just food for thought. Let us know what you find.

 

i had this ticking on my 93 ls also. it had 125k on it. i just let it go cuz i really
didnt want to get a valve adjustment. but then i cant pass DEQ with my broken egr pipe.
so when i replaced the pipe, the ticking went away!

 

Hi, did you find out what the issue was? I am having similar problem, after replacing timing belt and camshaft seals on my 99 LS the engine has a terrible tapping noise, sounds like a diesel engine, timing is fine. Car has not lost power and drives smoothly. I can't figure out why the tapping valve noise.
Thanks
