I just installed 7" lift on 15' Sierra Denali 4x4. I saw your post explaining the magneride/auto ride adjustments. The kit came with extenders rods, I placed on front. However, it's sitting 3" taller up front than rear.

Could I get some info on your Lifted Denali. I have an 07 that I would like to lift and am not finding any solid information.

Check my Albums, I added info on the Duramax Suburban

USA standard gear premium master rebuild sent Yukon gear and axle. It has all timken bearings and yukon multi lip seals. Comes with everything you need except new adjuster locks. If you are 1 of the lucky 1s don't mess with the adjusters until after you verify they need to be adjusted. Also the bearings in the adjusters should be drove from inside to out removal and install to avoid knocking the adjusters out. I wish I knew that before hand saves a lot of time!!! If they've never been adjusted they're probably still at factory adjustment and will be within backlash tolerance. If you have to adjust it you'll have to press the adjusters out and install new locks.
This is the walk threw I followed. It was very good just remember what I said bout the adjusters.

Thanks for the feedback extreme! I would expect it to be related to driveline and glad you fixed it. I will rebuild my front diff soon with new bearings and seals for preventative maintenance.

Oh hey man vibration was my front Dif carrier bearings. If anybody ever ask ya bout that 1 again lol!
Suspension settled in to around 39.5" in the front and around 40.5" on the rear! Rebuilt the front Dif. Due to a bearing failure and my vibration problems went away lol. 1hr down, 3 hrs to rebuild it, and 30 mins back up.

Haha I guess the tq of the the 6.0 is to blame sorta JK more like AWD.. A buddy was on his way home 1 day and we caught up on the blacktop. I pulled up beside him and stepped on it! He said the ass end squatted BAD and the front unloaded and the tires started riding on the outter edges!!! I bet if it wasn't AWD I wouldn't feel it... I think I'm going to lower the front a bit. I really don't feel like cutting the uca stops off or scattering the front dif or Tcase!!!

No vibration at all in my Yukon, I would assume it would be related to the front driveshaft

So do u have vibration at full throttle? With keys cranked up? Is that driveshaft or UCAs causing that??

Sure man what can I help you find or learn?
