Hey guys, new to the forum, came to ask a question. Did a bit of searching and could not find the answer, so pardon me if I overlooked it.

I lifted my 2007 Wrangler X 2-door with a TeraFlex 3" suspension lift. I put on 35" tires at the same time. Ever since, though, I've been getting a rattle when I accelerate aggressively in 1st/2nd gear up through about 35mph.

My local Jeep club has given some input, and the idea seems to be floating around that the pinion angle is off to much. Does this sound reasonable?

THe best solution that has been floated to me has been to replace the stock rear-upper control arms with adjustable ones so that I can rotate the axle to get a lower angle.

If this is indeed what I need to do, does anyone have the specs on how far this should be rotated? I am not very vehicle-savvy, but I am learning. I'd just rather not do trial and error with $300 at a time!

Thanks for the help guys!

 

thats definetly what you need to do,

If not your shafts going to explode. with that much lift, you might wanna considering installed a new U-joint style driveshaft.

 

I was just looking at the Reel 1310 drive shaft. Easy enough for an idiot like me to bolt on? I don't feel comfortable with pulling pieces apart that can get messed up, but take off, put on... I can do that.

 

Yes if you get the OE replacement from them, it's a straight unbolt then bolt in the new one.

 

its very easy, even if you upgrade and change the yoke, its easy.
