This has been a problem for a few yrs now. When I try to climb a sand dune, the front end starts violently shaking when the front wheels start spinning. As the title says, it feels like axle hop, but from up front. Needless to say, this causes an immediate loss of forward momentum.
Things replaced:
All new bushings in stock suspension - no effect.
RE LCAs with first iteration of lift - nothing
RK 3 link, uses new frame side control arm mounts and all hard joints - just tested it yesterday on a dune, problem still there.
Along with the 3 link, I also put in some Brown Dog poly motor mounts. Stock mounts (driver's side really) were shot anyways.
I'm running an HP30 with 4.88s, open and stock axle side control arm mounts with RE5.5" coils and blown RE monotube shocks.
Out back are RE 3.5" leafs with JKS 1" Boomerangs and 2 more blown RE monotubes. Not too impressed with the shocks...They're only a year and a half old. Leafs are the same age and I have developed gangster lean. My sagged, warped stock leafs did the same. Both leafs appear fine, but they didn't lean at all a year and a half ago...this is a fairly new development. Also, there's a loud thunk over any kind of "whoops" (smooth and less than a foot high) at anything over a crawl. Sounds like bottoming out, but I'm not sure that's possible with the amount of travel I tend to get back there. But, this is also a new development. The thunk is loudest on the pass side, same side it leans to.
Any ideas?
