Default Rear sysoension knocks

Put a RC full leaf 4.5 and shackle relocation kit on. When I hit a hard enough bump the suspension has a hard abrupt knock. One for every hard enough bump. Everything is torqued bolts aren't hitting the unibody.Not the hatch. What could it be? No other xj I had did it.

Check the bushings in the shackles.

knowing RC, probably a bad bushing.
but check to see if your exhaust isn't hitting anything, shackles hitting, broken bar pin in the rear shock, u-bolt/axle loose....

very likely your shocks do not have enough travel. get some extensions.

I have their shackle relocators and leafs. In my case when using stock shackles the shackles hit the sides of the relocator during uptravel. (I fixed it by trimming the relocators) Look on the sides of the shackles to see signs of wear on both sides of the shackle. If you have them set at a 45 degree and using stockers I dont see how they wouldn't hit.

No I've checked. No signs on the bracket or bolts. That's why I got the kit to begin with. Because the shackle was hitting the unibody, but now I know it's not hitting. I do think it's the eyes in the shackles or the spring, but I'm not about to tear it apart and check today. Lol
