Hey guys new on the hummer posts but have a few questions!
 

I have an 08 h3 with a pro comp 3" lift
Im getting some noise up front like a rawrring noise if you will only around 55-58mph...i cant figure it out...i noticed theres a very very slow leak out of the right cv axle so i changed the seal and front diff fluid. also i replaced the u joint at the front diff but still the same problems...my tires are getting worn down and i dont think that would be it...and if it were a wheel bearing wouldnt it do it more often..oh yea and this noise occured b4 the lift was put in! thanks guys..

Also i want to go with a 315 75 16 on the stock rim,and a light bar on the roof ? any suggestions

Appreiciate it everyone!

Also No vibrations at this speed...it just goes whooom..whooom...whoom...whoom
