Quick Question about rear UCA's

I had my jeep into my trans shop getting a detroit put in the rear. He mentioned to me that my rear pinion angle is pretty severe. I only have a BB on right now. Is this something I should worry about or is he just being a little too picky. I dont have any vibes right now. Should I get adjustable UCA's to fix this? I want to stay away from a transfer case drop kit. I was thinking the UCA's would be temporary till I can afford a better lift and an SYE kit. Thanks for your time.

the pinion angle is ok. you don´t need adj. UCAs. you only need them with a SYE and CV driveshaft.

With only a 2" lift, he's blowing smoke by saying your rear pinion angle is "pretty severe". A 2" lift doesn't actually change the pinion angle but it very slightly increases the angle between the pinion shaft and driveshaft. If you don't have vibes from that slightly increased angle between the pinion shaft and driveshaft where the u-joint is, don't worry about it. Upper adjustable length control arms are needed if you're installing a SYE and CV driveshaft but since you have neither, you don't need to adjust the rear pinion angle.

At most, if you had some minor vibes from your 2" lift, a simple 1/2" or so transfer case skidplate drop would take care of it for the cost of washers used as spacers and perhaps longer t-case skidplate bolts if they are the newer metric bolts that are shorter.

If it's not broken...don't fix it. Don't waste a lot of money trying to make a correction unless you need it.

If you do have minor vibes, you can try dropping the tcase skid couple washers. It wont hurt anything but lower and most likely eliminate drive train vibes.
