Hey everyone,

I found a lot of threads about this, but they did not exactly give me a good answer. I recently noticed both my CV shafts are busted and one just started to make a knocking noise. Someone suggested dropping the differential because my CV angles look a little too steep. Any suggestions on that? If so, where to buy the drop brackets at? Suggestions on brands od CV shafts? Anyone else ran into this problem and how did you fix it? This is not my daily driver.

I have the RC 2.5" lift, 2" body, add a leaf, and a little t bar crank on 32's.

Really appreciate it.

 

doesn't the rough country 2.5in lift come with a drop diff kit? But yes it would benifit from being dropped

 

After doing some research, apparently the older RC lift did not come with the drop brackets. They are making me pay for them since I purchased the lift over a year or so ago. I really wish RC would just sell all of their parts individually instead of as kits.

 

id try getting rid of the torsion bar lift first. if you notice wear happening,then look into the brackets.

 

I wanted to update on this post... The RC lift had the drop brackets included, and I did lower the T bar crank a bit. And I recently just broke ANOTHER CV shaft driving on pavement. It's been less than 1000K since the replacement.

 

How severe is your CV angle? If you can, post up a picture for us. Did you test for any binding at full droop? Especially on the passenger side.

 

It would be nice if you just get the drop brackets

 

That's the problem. Front chassis ride height is out of spec. Until it gets back in spec, CV joints, along with other steering & suspension parts, will continue to wear out prematurely.

The vehicle must be on level ground, do not raise the vehicle during measurement. Here is how to measure it.






Spec is as follows:

1996 & newer:

4WD (except ZR2) = 4.6” to 5.0” (4.8” is preferred)

4WD ZR2 = 4.6” to 5.2” (4.9” is preferred)

Adjustment is done by rotating the torsion bar adjusters. Clockwise increases, counter clockwise decreases. The easiest way is to measure from the center of the lower control arm pivot bolt straight down to the ground. Then measure from the knuckle straight down to the ground, and subtract it from the pivot bolt measurement. The result is front chassis ride height. When your done, the vehicle needs a wheel alignment.
