Vibration

[Crcz71]

Hey guys need a little help. If this is not the right spot for the thread sorry wasn't sure where else to put it. My issue is I have a vibration from the rear mostly 60 to 65 mph. I've replaced rear calipers pads and rotors. Replaced u joints this weekend and it has seen some improvement. I've rotated my tires front to back and cross crossed them. I'm running fuel wheels with Atturo 33 12.50 17. I have no shake or issues with the front at all just the rear. It also feels like it's coming from the right rear. I have not replaced the shocks but that's next. The vehicle is a 04 z71 has leveling keys in front and spacers in rear. Any info would be appreciated.

Did anything change with the tire rotation? Most vibrations at that speed are from tires...

 

[Crcz71]

No it didn't. That's what is confusing. I thought tires as well. I rotated them a couple weeks before replacing the u joints.

What size rear spacer? What are your fender measurements?

 

[Crcz71]

can't remember I'll measure my fenders at lunch.

Bottom of fender to the ground 39 5/8

Ok so your height isn't any issue on pinion angle based upon fender heights. I ran my old Yukon at 39-40". So what wheels do you have on the hoe?

Fuel and I'm not sure which ones ha. I can get some pics in the am

 

[01Konvict]

Well if there fuel then its a dual drilled 6 lug wheel. Are you using any hub centric rings to mount them on the truck?
