![Question](https://www.clublexus.com/forums/images/icons/icon5.gif)
I have a 1994 LS400 with Rear End vibrations and then in the past 2 weeks I am getting an occasional loud clicking noise from under rear wheels when going 0-10 miles per hour with each revolution of the tires and just noticed going over potholes now it sounds like louder noise from rear with each bounce. I just today jacked the rear end up and could actually move the differential and driver side rear axle connection easily with one hand....the differential is scary loose! I plan on replacing diff mount or mounts? (not sure how to do this without instructions and have searched on CL??? Anyone have instructions with Pictures?) and posters have also said to replace transmission mount (lexls has good instructions for this with pics). CAN ANYONE TELL me, is the connection at the axle to the differential supposed to be really flexible....or is that just because it seems like the diff mounting system is almost entirely off or broken??? ANY HELP OR ADVICE, INSTRUCTIONS WOULD BE GREATLY APPRECIATED, I FEEL LIKE I NEED TO DO THIS TOMORROW BEFORE THE AXLE BREAKS AWAY FROM THE DIFFERENTIAL OR VICE VERSA. Thanks because this really scares me and seems dangerous and hope all are having a Great Thanksgiving today.

Thanks for your feedback and question. I did check between the driveshaft and front of the differential and I think that bushing is called the propeller shaft bushing, not sure. But mine is solidly connected and appears to be in very good shape. I'm going to be spending some more time underneath it today and will post results. Thanks again for the suggestion

My 99LS has 205K miles, I know my engine mounts are shot, already got new engine mounts and transmission one too, will be doing the job one of these days.
My thinking was to look into changing flex disks on the prop shaft, diff. "arms" bushings that are on sides and diff. rear subframe cushions. The latter ones call for SST's.
09570-22011: $423.65
09527-17011: $85.39
Anyone changed those and want to share experience? Are there cheaper substitutes for the SST's?
And if I do get the SSTs, can they be used for other bushing jobs or they are for that specific rear diff. bushing job only?
Thanks,
Val
