I own a 1995 LS400 and have a rattle under the hood that is driving me nuts. I have replaced the struts, strut mounts and sway bar links. I have tightnened everthing I can think of and cannot find the rattle. I even replaced the transmission mount at the rear of the transmission. When I drive over even the smallest bump I hear a rattle that sounds like it is coming from the suspension. I realize this sound could be coming from something else but where?? Please help me locate this rattle.

 

strut bars....

 

If the strut bars are fine then check the caliper bolts - sounds stupid but I had the same noise in my 95 and discovered my caliper bolts were not torqued. Easy to check.

 

...did you check to see that these are in place?? They hold pressure on the pads. The brakes would work just fine w/o them so they may be easily overlooked during a brake job.

 

possible. ask parts dept. for shim kit
