Hi,

I was hoping someone could help me out. I have a 99 deville with the rear air ride. The top rubber mounts of my shocks seemto be worn out. I figured those are easy enough to replace, but when ever I try to loosen the top nut, the entire shock is twisting.

I have removed the bottom bolt in order to avoid twisting the rubber on the outside of the shock, as they are not exactly new either.

Any suggestions?

There is spot for TORX bit on the end of the shaft to hold the shock from turning. Its a big one and get the shock end cleaned out real good so fits good and don't strip out. Otherwise its vise grip time. Pics on this site somewhere.

There will either be a hex area at the top of the shock shaft (for a wrench), or a hole in it for a Torx bit driver. You hold the shaft still in one of those two ways, and use a wrench to loosen the nut on the mount.

hmm, it is always so easy in theory :) No way this is coming off without damaging the shock. Guess i will leave it be till the shocks need to be replaced. IMG_20150403_143550.jpg

How old are the shocks?

If you replace the shocks as well, you don't have to worry about removing that nut.

Doesn't this nut have to be removed in order for the shock to come down from the top?

That looks like an Allen to me, not torx. You can clearly see the flats.

This. Expose and put a pipe wrench on the shaft. Either the nut will break loose or the top of the shaft will snap off.

Well, as of right now, I am not going to replace the shocks. Thus I will leave it alone for the moment. If i was going to replace the shocks, I would simply cut the nut off.

The best deal for the ACdelco shocks i found was on rockauto for ca. 260 for a pair (no RSS)

the Monroe 40046 is a better shock -

Do you get just as smooth of a ride with them as with the OEM ones? I am really looking to get the smoothest ride possible.

I have never heard anyone complain about the ride -
but - keep in mind -
a new shock will ride firmer than an old worn out one -
