Clay in the carrier...

[Waterloo]

Well, get that fixed asap if there is excessive play, I had mine fail, thank God in a parking lot... If I would have been driving, that would have been a mess. It felt like someone nailed 2x4's to my drive tires. If that driveshaft cuts lose, the damage can be catastrophic. Just ask Rawze. If you have any question on that carrier failing, fix it NOW! Do not drive the truck. Mine was fine, and then BOOM! No warning.

I had to have the truck towed to a shop, I could not drive it, where we discovered not only the bad carrier bearing but the u-joints were toast too, even though they would take grease. It was a $2200 job, redid the entire driveline, sent the drive shafts out to check for balance and one had to have the yoke removed as I had a bit of lot rot, it was not coming out using normal methods. If that truck of yours sat for awhile, you may be experiencing the same, lot rot.

For that carrier, FleetPride should have one, then on mine, there is a one time use crush washer behind the yoke, along with the nut at the yoke on that front diff. The torque values are stupid, like 900 ftlb. I have the Meritor driveline, not sure what unit you have, but that is something you should ask about. I take that stuff to the shop.

Recently I had the that pinion seal go on me, I bought the parts and made sure everything was replaced with new, the washer, nut and seals. I found the seals at the dealer and the rest at FleetPride, both carried the Meritor brand parts, I won't install knock off parts in these critical areas.

And if that dealer will not give you part numbers, find another one to deal with.
