curious why a 5x5.5 kit over 5x4.5?
Did you run 5.5 in the front and 4.5 in the rear?
IF that is really the case, then I have to do a 5.5 myself which means I will wait till tire time because I just bought 31's then a few months later 33's and a few months later now. I just can't buy another set of wheels and tires yet haha.No, I am saying that the 5x4.5 kit makes the front track 1.5" wider (3/4" per side). The 5x5.5 kit does not.

I would suggest having a reputable shop check out the installation of the gears and check the whole drive line to get to the root of the problem as well as having your tires balanced
I’m going to guess you didn’t read through the entire post.....
I'd like to see a picture of that jeep those wheels look terrific.I also have the Yukon 5x5.5 manual hub conversion. I chose it over the Yukon 5x4.5 manual hub conversion kit for three reasons: 1) Bigger and stronger than the Ford style 5x4.5 hubs (although @mrblaine observed that in practice hub strength of the 5x4.5 kit isn't much of an issue); 2) I didn't like the idea of the 5x4.5 kit widening the front track 1.5" with no good way to match the rear track (although @mrblaine informed me that he actually prefers to set up jeeps that way rather than equal track front and rear); but most importantly (3) I was able to get a killer price on the 5x5.5 kit from Amazon that was $650 off retail and $400 less than the 5x4.5 kit. In the end I had to purchase $525 worth of new wheels with the 5x5.5 lug pattern, offset by the $400 I received for my old wheels, and it cost $75 to remount and re-balance my existing tires, so I really only saved $200 over the 5x4.5 kit.
Do I regret my choice to go with the 5x5.5 kit rather than the 5x4.5 kit? Absolutely not.

That seems like it is better with my narrow 8.8 rear.It’s not IF it makes it wider it DOES make it wider. The spindle adds about 1/2” to the width, and then they reuse the stock rotor and add the outer portion of the hub to the rotor that is 1/4”. The 5x5.5 kit uses a CJ rotor and they shorten the spindle up. I measured everything and it was actually 1/8” narrower per side than the stock set up so 1/4” narrower overall

The spindle adds nothing to the width or takes away nothing from either. It is just the carrier for the bearing hub in both kits.It’s not IF it makes it wider it DOES make it wider.

I've been there so many times I can't believe it's the pinion angle causing the vibes.
If the vibe is still slightly there, angle the rear down by half a degree or slightly more.
Took the rear drive shaft off today and went for a drive. Vibes are virtually gone. Just a slight vibe at 75, but nowhere near as bad. So, I checked torque on both yokes and will put the rear ds back on and double check pinion angles. I've been there so many times I can't believe it's the pinion angle causing the vibes.
Any other recent changes at all other than the tires? If it's just pinion angles then this saga can come to an end quickly. Keep us posted.
