I had some issues with loud clunking that was really bad in 4wd few months ago, pulled the front shaft thinking it was u-joints in that, turned out to be passenger side axle u-joint. Replaced that and have been riding with no front shaft for about a month with no issues.
Heard snow was coming so i put my front shaft back in last night- only to find a similar horrific grinding noise when in 4wd, and slowly turned into a tick in 2wd. Looking for suggestions as to what it might be.
Replaced the passenger front axle u-joint, driver's side appeared, and feels solid. After replacing that my initial clunking stopped. Replaced the front u-joint on the front shaft, the two in the CV portion looks and feels solid. Also replaced both u-joints in the rear shaft, since one was cracked.
The "clunking" exhibits the same type of noise a toasted u-joint does- a clear 'clunk-rotate-clunk-rotate' that increases intensity with speed, and not with engine RPM. When the front shaft was out, no abnormal noise was made when placed in 4wd (granted yes, there was no load).
About a month ago i stuck my finger in the front diff to check for fluid, remember there being plenty, and a slight silver color. Worse case scenario here i'm thinking is the front diff is toast. Aside from pulling the front cover (currently snowing like a bitch), any other tip on confirming blown gears?
Any input is greatly appreciated.
