Not sure what you mean by "slams a bit" If you replaced a shock and the side on the rear is still "slamming" it could be a different part / bushing causing the problem. The shock upper mount is a common ware part and it is very bad, will cause even the new shock to not function correctly, Please see the video attached below:Hey all.
I recently replaced my rear driverside shock because it was the worst. The side sagged, slammed when hitting bumps, and was generally uncomfortable. Being on a budget however, I'm replacing one shock at a time. Is this a bad thing, outside of consistency?
I just replaced that shock on Friday and have noticed an increased comfort in that corner lol, but I think the other shocks not being the greatest either are are putting a damper (pun?) on things. The rear still slams a bit going over bumps, but it almost feels like it's still in the corner that I replaced the shock. No idea why.
Also, as stated, you need to replace them in pairs rear / front, or you will compromise the geometry of your suspension in ways that will cause many kinds of control problems. I understand the $$$ thing, just trying to help
