J arm hitting frame!!!!!!!!!!!!
Hi all. As the title says my J arm is hitting the frame where the bumpstop is supposed to contact the frame. I have the stock bumpstops and surly this is not supposed to happen with stock springs. (I have 3" procomp springs in front) I was driving my drivers side wheel up a snow pile to see how much flex I was getting and my J arm hit the frame. I know that the 2" longer than stock shackles I was testing pointed my pinion down about 2.5 deg so this is a factor but still this should not happen. now I'm starting to think the axle is bent, but it could be the j arm... What do you guys think. Thanks in advance for any input.

Picture(s)?
What do the bump stops look like? Might be the springs are in backwards (assuming they are not a symmetrical design). |
The bump stop looks exactly like this one but it says 100 on it and the passenger side one say 90. I'm assuming it means 100mm and the 10mm difference is the difference in mounting height on the passenger side.
