What's goin on all my Lexus fans. This website has helped so much over the last 2 years on my LS400 and this is my first time posting. Did the timing job and all my front suspension replaced. Little things here and there like the brakes and trans filter too. Has had a welded diff for about a year now still rollin strong and just slapped Megan LP Street coilovers on. Such a reliable car.



Recently its had this small vibration at idle. It gets a little worse at highway speeds. I changed all 3 mounts but not with OEM. They are hydro fluid filled tho. Could it be fan and/or fan clutch? Also have dreaded egr pipe leak

 

change the trans mount for the vibration.
the EGR pipe was a pain to replace but not impossible. I did it on my 97 with just removing the pass side exhaust.
being in CA, we don't have to worry about rust, but be sure to spray PB Blaster on the hardware before trying to loosen, to lessen the likelihood of stripping.
