Anybody ever used this bump stop from the company Energy Suspension to relocate their rear end “center top” bump stop? It’s part # 9.9150G. Here is an old forum quote (the link is broke but if you manually enter the part # it shows up) from 2002 which is an answer to another person having his pinion yoke chop a piece of his bump stop off.

“O.P”
“I was driving recently and hit a large pot hole in the road (just missed it I guess). Anyway, I heard a noise from the rear end that sounded like rubber popping. I looked under the car and noticed that the bump stop on the body directly above the the rear end had a notch cut in it. I have put on the 3/4" extended rear links and have really liked what the do for the car's handling. I am certain that the pinion ring on the input to the rear end made this grove. Has anyone else had this problem?? If so, what did you do to correct it?? Please let me know. Thanks!”

“I did allot of research on this and found that using the Enery Suspension Bumper Stop # 9.9150G our problems are solved. It is slightly offset which keeps it off the Yoke. It is also a little higher to allow the use of the larger diameter driveshats. Otherwise they can hit the floor pan when hitting a big bump in the road or when carring heavy loads.
Here's a link: http://www.energysuspension.com/bsp2.html
Hope this helps!”

This is exactly what I’m looking for (if it works) because I’m on the edge of deciding/purchasing extended rear control arms (Metco) and a larger 3.5 inch Aluminum driveshaft (3:73 gears). I didn’t want to see if I can get a reply from a post that was so old. I know I shouldn’t totally depend on one piece of rubber (I’m planning not too) , but it helps me not destroy my existing rubber bumper. I want to know if this part really repositioned the contact point to the correct place on on the axle away from the spinning pinion yoke. Also, for anyone looking for a remedy to the same deal, here possibly is a part. That bolt don’t look like it’s off centered 3/4 but it might be. Anyone has firsthand with this part, feedback appreciated. Notes: I guess it’s a pair for a Buick both sides originally.

Thanks.

People use various things back there.

While it is not offset , the longer progressive ZQ8 S10 front lower arm snubber that a lot of us use on the front works very well as a pinion snubber . That is what I put on when I had a 5 inch shaft in the wagon.
Its still there .
This does not deal with the extended arm deal, but you are not doing that now anyway

95wagon - Any dimensions on that S10 snubber? 15956547
Unfortunately I will not be near my car for at least a week.
Googling that number though, many threads with some dimensions do show up.

Those
those (the white ones) are the ones I installed in my front end. My old ones were chewed up really bad. It took me a while to find the part number on the forum but I did. It is an s10 bumper and doorman too when it arrived. I can’t remember the part number. I do have it on a receipt filed away. It took me a while because the old ones were the same ones. I didn’t know they were not stock yet because a previous owner Installed them.

Can't say whether the gm number is still available or not at this time of night but it sure shows up for sale in a lot of places.

Not the easiest solution, but I just welded up a new box for the pinion snubber to sit in that moved it back. I also extended the spring perches. To me, the biggest issue with extending the rear control arms, other than using upper arms that don't have an offset clevis to correct for the new angle, is the location of the spring perches. When you extend the arms 3/4's , you're also moving the spring perch back that same amount. It just didn't look good at all to me having the spring perch completely offset from the spring pocket like that.

You guys probably already know this. I didn’t. They sell adjustable pinion snubbers for those who didn’t know. Only thing is if vibration has the pin and clip rattling that would be annoying. Something precise and maybe greaseable would be nice. I’m just putting it out while we are here. Photo of googled “adjustable pinion snubbers”
