Is there any problem changing the rear axle pinion angle to line up more correctly with the ds eliminating the steeper ds angle while keeping the factory drive shaft?

I have about 3" lift on my 2 door and need to reset the rear pinion angle as I have pretty steep angle in the factory drive shaft. I will eventually install an after market ds but until then is there any problem doing this?

Does changing the pinion angle "buy me more time" with the factory drive shaft?

Thanks.

 

Nothing wrong with that at all. I did the same with my Jeep and so have many others. Having less angle will help extend life of your DS too also when you upgrade you can just pop in the new shaft and your good to go since you already aligned your pinion with the drive shaft.

 

When you rotate the axle to compensate for the pinion angle, the springs bow out; the rear trackbar mount moves; and your rear brake lines may need to be extended along with your shocks.

So there aren't problems, but other considerations you need to be prepared to address. So you'll start with adjustable upper control arms, but an adjustable rear trackbar and extended rear brake lines should also be on the list. Relocating the rear spring pads and longer shocks may be required as well. But with 3" of lift, you shouldn't have to worry about the latter issues.

 

Oh and yes, it helps to prevent premature wear of the driveshaft at the axle end, but the factory output yoke for the t-case will still be at a steep operating angle. But again, with 3" of lift, you're probably in a safe zone.

 

I had kinda figured on needing to install adjustable rear upper control arms and wedges to keep the coils from bowing.

An ongoing project...

 

Getting ready to do this also. I read that the sway bar links may hit the axle, or something? Anyone had any problems with this when rotating the rear axle pinion?

 

Just did this over the weekend. Installed adjustable UCAs and rotated the pinion angle to a much better angle. I will try and post pics soon. I followed the write up on project jk and am happy with the ease of the job. Actually I find the most irritating part of working on these JKs is removing and reinstalling the tires. LOL

The only issue I had of anything making contact with anything else was the frame side track bar bolt was contacting the edge of the passenger side bump stop block. A little grinding on the block and problem solved. The ONLY reason this happened is due to the TF track bar reloacting bracket I previously installed. If the frame side of the rear track is factory, you should not have any issues.

The pinion angle is waaaay better but there is still a bit of steepness in the t-case side.
