yes, but you can use the bottoms to adjust them too. If you can only afford one, get the uppers

 

right, the only issue with the front is on the Auto tranmission. It hits the skid plate.

 

Thanks for all of the quick responses and good information. The dealership is saying that the rear pinion angle exceeds the Chrysler specs and that is what is causing the problem. They also told me that shims would need to be installed to adjust the pinion angle to correct the problem. It may just be me but I don't think shims would be a good solution. It sounds like if they knew what they were doing they would have suggested the adjustable control arms instead of something half A$$ like shims.

Does anyone have any suggestions or opinions on adjustable control arms? I know , Daystar, Teraflex, JKS, Full Traction, Black Diamond and Skyjacker all make control arms for the JK's but does anyone have any recomendations. Also, if I understand everyone correctly it is the upper-rear control arms that have the most effect on the rear pinion angle therefore those would be the ones I would need to replace first. Is that correct?


As of right now the Hayes dealership has completely voided my Chrysler powertrain warranty and I am fighting with them to try and get it back over to the Stone Mountain dealership whos says they will fix it and try and get my warranty reinstated.

I'm gonna need a few drinks tonight!!!

Thanks for everyones help!!

 

Hayes dealership knows what they are doing most there belong to a jeep club cant remember the name.He told you shims as that is the cheap way, but you really need adj control arms and an after market drive shaft.The shop manager at stone mountain has the yellow lifted JK on 33's pretty nice guyIf you need a stocker untill you can buy an after market one,let me know what you are willing to pay for 1.

I have the unlimited so my old stocker wont work sorry, i wasnt thinking

 

shims? this isnt a YJ. Unless they put a cam bolt on the control arm, they wont be adjusting your pinion angle.

all the control arms you mentioned will fix the issue, i'd avoid skyjacker, but thats just me. I dont see how they can avoid the entire powertrain warranty, maybe just the driveshafts and parts that are effected by the lift.

 

I just read you profile, it says 4" of lift? Did they put track bars with this lift? trackbar brackets? its a really big difference between 2.5" and a 4" lift.

 

The shafts are a part of the 'powertrain' so if you are causing stress to part of that system like pinion angle to the shafts I can 100% see them telling you to pound sand. They aren't going to subdivide and breakout certain parts of the powertrain warranty for certain people/mods. It is obvious that a lifetime warranty isn't the most profitable thing for a car maker to offer and it should also come to no great surprise when you tip toe a fine line allowing them to cancel that obligation, they will. My guess is that once the void has been placed on that guys VIN it is not possible to have that decision reversed. My advice is to get the proper shaft for the lift and stop having the Jeep in the shop for a problem that is easily preventable by doing so.

 

The lift I have on my JK is an Omix/Rugged Ridge 2.5" lift kit. Of course it wasn't until after I installed the lift kit that Omix told me that the 2.5" of lift was based on installing it on a 4 door JK. This being said after everything was said and done the actual amount of lift I recieved from the 2.5" kit was about 3.75". The kit came with shocks, springs, trackbar relocation bracket, bumpstops and rear brakeline extension brackets. I was not aware that this kit would give me as much lift as it did when I bought and installed it. Nor was I aware that it would cause the issues that it seems to be causing. Maybe next time I should do a little more research.

Maddygirl, Thanks for the advice and I do agree with you. I'm going to try and get the proper driveshaft and new adjustable control arms installed to try and eliminate this problem. It's just a long frustrating process when dealing with the dealerships sometimes.

 

So your saying, his engine warranty will be voided because of a lift? no way. He needs to fight it.

 

I assume they're just talking about the suspension components

Not engine/transmission.....

"Powertrain" does include all of that.....I would definately fight it, if they try taking away the warranty for anything but the suspension..
