I have a 2017 Cougar with the vault hubs on them. One side the rotor was galled, BCB replaced the assembly. Then the other side did the same about a year plus later. I wound up calling Dexter. First time I spoke with someone out of California, waited a while and finally got some parts, not everything. I then called Dexter again, talked to a Customer service agent out of Indiana, he sent me everything plus that fit my trailer. Installed everything, and used the lube that they sent. That stuff is messy. FYI don’t forget to pull the zerk off after you finish filling the hub with the new lubricant as you will be taking the cap off to get that zerk back and repacking the cap.
Incase you do not have numbers, and for those that do need them here are the numbers for the kits that I received from Dexter:
Bearing and seal replacement kit 3.2 K & 3.7 k n1.980″ outer bore K71-059-00
Brake Pads (stamped on pads) DH-LH-FF
Race (small): L44610 Bearing (small) M56G20AE28
Race (large) : L68111 Bearing (large) L68149
The seal does not have a part number on it, mine all came inside the kits.
Check your brake pads as mine came unlaminated, yes even the new ones. Hope this all helps.
