Replacement Hub Bearing Kit Needed for 4,400 l Axle on 2021 Grand Design 2670MK Travel Trailer


I own a 2021 GD 2670mk TT. I have 4400lb tandem axles. I can only find bearings for 3500 lb axles. What is the part number for the bearings tapered and races for 4400lb axles? Thank-you?


Expert Reply:

A lot of the 4,400 lb axle will use the bearings and seal kits for a 3,500 lb axle so if that's what you have then the Hub Bearing Kit # BK2-100 is the correct replacement kit.

The 4,400 lb axles can be a bit hit and miss though so you'll need to either pull a hub to check that you have the matching parts that come with this kit (see list below) or you'll need send me a photo of the axle tag so I can see what exact parts you need.

Bearing Kit Parts:
Inner Bearing - L68149
Outer Bearing - L44649
Grease Seal - ID 1.719" and OD 2.565"

Attached is an installation video for you to check out.
