Bolt hitting flat bump stop....

i was hearing a knock from the right rear of the vehicle every time i hit a medium bump (like a speed bump in a parking lot) at 5 mph.

happened out of the blue one day - after doing my lift.

my boss, in a suit, got on the ground and noticed that the flat black bump stop pad in the right rear was making contact with what i think is the rear trackbar bolt. the pad sits just to the left of the right spring and is directly below a white bump stop.

For some reason, whoever put the bolt in, did so where the bolt points toward the front of the vehicle. indoingso, the bold was making contact with the pad. the top of the pad showed signs of light damage right where the side meets the top. i felt behind the track bar (and i could be wrong...might be the sway bar (1st jeep, my apologies)... either way, the bolt was sticking out about .50 inch. when the suspension compresses, the bolt hits the pad. at first i thought about swapping the position of the bolt (make it face toward the rear). i didn't have an impact wrench so that wasn't going to happen. i ended up shaving a bit off the pad - not nearly enough to where it affected the surface area that comes in contact with the white bump stop.

Took her out for a hard run, including speed bumps at 20 mph... no noise what so ever. .

is that a common problem? should that bolt been put in different direction?

For what it's worth, I had the same problem with my rear track bar bolt hitting the bump stop. I tried turning the bolt around and it still contacted. So, I ended up shaving down part of the bump stop. Oh, Rock Krawler 2.5" X-Factor lift with Teraflex rear bump stops.

I just ran into this problem when I put my RK X-factor rear control arms on with an AEV 2.5 lift. The bolt head (head forward) strikes the bump stop block AEV supplied because the X-factor arms push the axel back about an inch or so....

A friend who has the whole RK lift, has offset bump stops that lean forward and avoid the bolt head...
