Rattle from rear
*warning* Could be a bit long to explain in full****
May be a minor thing to some but its been driving me ****ing bananas for a year.
Last spring I put on my PMF lift, including 8" traction blocks/bars. When I installed, my leaf spring center bolts fell through and into the big blocks!! Lol
I mavgiver'd up a temp solution (rebar) til I was able to get new bolts. (couple days)
I never had C-clamps so when I went to put in the new center bolts my leafs spread apart, no big deal got bolts through lined up and set in the alignment hole in block..this is where I frigged up...I then tightened while weight of truck on leafs/block etc. These bolts are soft and not gonna take well to too much torqing.
I got them as tight as I can but not sure how well and then stripped the threads off bolt so nut just free spun... I had top plate torqed down pretty tight, everything else tight.
Fast forward to this weekend. New bolts. Installed and tightened while removed from blocks. Top plates torqed to 100ft/lbs.
I get a very annoying jingle from the rear end of truck after bumps/potholes etc and seems to be on the rebound.
Ive tried damn near everything.
Ive been under truck numerous times with rubber mallet, ive had 3-5000lbs of gravel in the box thinking weight might change it, no spare tire under box. I 1" ratchet strapped exhaust in a few places to see if any change...nope. Doesnt change when brake applied. No hitch in the receiver, exhaust hangers all in place and in good shape..same for shocks (which are new too). Fuel tank straps solid/good shape. Trying to think what else.... Edit: Tailgate seems solid, side steps are noise free...
I cant replicate the sound any way either.... jumping on rear bumper, smacking everything with mallet.
Im at a loss.....dont know what else to do/try. Didnt do it before lift. I still think its the leafs springs but not sure how or why....so my next move is to buy a new set of leafs......
Anyone want a truck before it falls down the bank?
