Default Weird wobble on launch after gear change...

Last Friday Night, when I would roll out of the hole, she was squirrelly as HELL... He rear-end wobbling all over the place... It felt like it does when your breaking loose, busting a rolling burnout through second gear on the street... But I had the Mickeys on and it wasn't breaking loose... but the rear-end felt exactly the same way... VERY LOOSE, requiring a fairly significant amount of steerage to keep her down the middle. She also wobbles when crossing uneven pavement, similar to what it feels like on a motorcycle when you're changing lines over uneven pavement.


Since we installed the 4.10s, I've (only twice in dozens and dozens of roll outs) had something pop up and slam the undercarriage twice... this happens only on the 1-2 shift, after she's been sitting and cooled down... and only under WOT.

I popped underneath and didn't see anything obvious... I long ago deleted the front sway-bar for weight and dig-traction when I was running street-radials, before the Mickey ETs... Also I have an adjustable torque arm coming... hopefully it'll be here next week.

Any thoughts?

lca bushings worn out? this would cause the rearend to go out of alignment and a possible "pop" noise under load. if so, get a set of relocators and a set of adjustable lcas... this will cure the problem and enhance the performance.

Man thanks VERY MUCH!

Couple of quick questions: LCAs... Ok... I'm gonna say these are the arms that go from the axle back towards the front of the vehicle and are what... 18" ish long?


Where would I relocate them too? There are kits for such, I'm guessin'?

# 1 yep
# 2 are 2 peices = kit, attach to axel at point where the rear of LCA connect, they have 3 holes which allow you to change angle of LCA
good luck, Johnny
