Do you guys have a heavy vibration at full speed... ??? On my mammoth the vibration start at about 60 Km/h and I'm not sure where it came from... this not a wheel or drive shaft unbalance because the vibration is high frequency (mirror get totally blur) Any Idea ??? MAX Sorry, if some time you don't understand what I'm talking about, I'M FRENCH... by the way, some time I don't understand what you say, it's probably because I'M FRENCH !!!

Is the vibe less when it is in 4X4 than when it is not? If it is it's most likely the front drive shaft. Aaron www.mammoth800parts.com

Make not much difference on 4x4... but I took a look at the rear drive shaft and it is really off center, on the transmission's u-joint the shaft is not bad but on the diff u-joint the shaft is off set by 1/4 inch... so it bounce about 1/2 inch... I think this is more than enough to cause that vibration !!!
