Bad axle u-joint?

[jeffncs]

When in 4H and driving in the snow, there was a rhythmic grinding sound. When backing up, the axle made a clunking sound.

Some more info…

Hubs locked 2H - no noise
Hubs unlocked and all t-case positions - no noise
Rebuilt driveshaft - all new u-joints and CV
I replace the gear set and bearings 2 years back but this truck (almost) never goes in 4-anything. I built this one for my wife and she just cruises around town.
Didn't touch the axle u-joints

Does my assessment sound right?

Adding - oil status - housing has oil. Clearly been spinning as it has that aerated appearance.



Note - the “sparkly” appearance is bubbles from spinning. Pinion bearing drag, pattern and backlash were all in spec so I’m doubtful there’s a gear or bearing issue.

Front d/s may be shot…. The slip joint has a lot of play both up-down and sideways, plus it also have a fair amount of rotational play.

Could be all of the above

I’m going to either rebuild my spare stock d/s, find a good replacement to rebuild, or buy a new one. Eliminate that along with replacing those worn axle u-joints. I hate the idea of going into that D44!

You hate it a lot less than waiting and you need it buy axles too after the joints fail. There is a smarter/brighter side lol

I’m gonna do it all over next week or 2. Ordered the axle u-joints earlier. Now hunting for a d/s. Guessing Tm Woods will see my CC swipe soon!

I ordered driveshafts from WH in the past and they came directly from Tom Woods Driveshafts.

Sounds like one knuckle is bumping (interference/clearance) the other knuckle. Just my $0.02 opinion.
