Are you regularly checking on your rear pinion seal and u joints? I'm saving up for a SYE, DC shaft and upper rear adjustable CAs too. I too have a MML and that was sufficient to eliminate my vibes after my 2" suspension lift. Unfortunately the vibes returned after I installed my UCF transfer case skid. I was able to remove the vibes once more, by installing a transfer case spacer/drop.

If you're still getting some minor vibes, I recommend dropping your transfer case a washer at a time until they are completely gone. This will save your u joints and pinion seal from a premature failure.

Oh yeah. I keep a set of 2 spare u joints in my glove box too I'm always checking them after every day where I'm driving a lot. I'll try the washer thing, gotta keep my frame nutserts from spinning first so I can get the skid down.

SYE/CV shaft is the best way to spend your money ever.

Don't forget the $$$ hardware required to adjust your pinion angle too .

It was kinda weird; when i put mine in, I had ordered upper adj. CAs and an angled track bar bracket, but after i put the SYE & shaft in (I was still waiting on the CAs to be delivered) the angle was perfect with the stock CAs
