Tackle a full hub service with matched bearings, races, seals, and caps. For a sure fit, read the bearing and seal numbers on your hub or measure the spindle at points B, C, and D with a digital caliper. Need extra protection or easy greasing? Options include double-lip seals, caps with removable plugs, and bearing protectors that keep grease under slight pressure to block foreign matter.
Yes—double-lip seals are a great upgrade over single seals, and caps that keep grease under slight pressure help keep foreign matter out. If inner seals have leaked on an E-Z Lube setup, switching seals and using these caps can help. Check your spindles for wear; Redi-sleeves can provide a fresh seal surface, but may need trimming so bearings seat properly.
Yes—replacing bearings, races, seals, and adding new dust caps can make older hubs feel like new. Removing original races was not an issue for a hub refresh. If your axle has built-in grease fittings, choose caps with removable plugs. After repacking, verify seals fit correctly and spin the hub to check for smooth operation before road use.
Pull the hub and read the bearing and seal part numbers, or use a digital caliper to measure the spindle at points B, C, and D. Ordering by camper info can lead to the wrong kit, so verify your parts directly. Axle ratings can share sizes in some cases, like certain 4,400 lb setups matching 3,500 lb parts, so measurements or part stamps are the safest check.
Yes, Timken bearing kits are made in the USA and we've seen genuine Timken bearings and races used. There are fakes in the market, so check the markings to confirm authenticity. If you're cross-referencing seals, match the dimensions and lip design; a Timken double-lip with the same dimensions can replace an equivalent double-lip seal.
