3500 HO Rear Wheel Seal Part Number

[secutright]

Good evening all. Sorry if it's somewhere else on this forum, I've tried searching to no avail. My 2020 3500 DRW with 6.7 HO has sprung a leak at the rear wheel seal. I have been trying to find the seal part number somewhere and getting a ton of conflicting information. TorqueKing says that it's a different seal for HO, which is the same as the 4500/5500 (AAM 12.0), but they must have built that thing out of solid gold, they want $100 for one seal... Everywhere I look up anywhere else it shows the part for the 3500 with 6.7 Non-HO or Gas version... Has anyone been able to find the actual part number to order for this? Or am I missing something glaringly obvious? Yes, I could go pull the hub and look at the number on the seal, but I would rather have the part on hand before I tear it down.

Thank you in advance for any help!

Scott

I would give East Coast Gear Supply a call. I had my gears upgraded to 4.10 by them and they pull off your VIN. If there's anyone who can help you those guys definitely can.

The 3500 HO does not use the same axle housing as the 4500/5500, but it does use the AAM 12.0.

The SO 3500’s use the same housing as the HO’s, but the R&P’s are different.
