I finished repacking the bearings on my Parkliner
(2014), so here is a step-by-step listing of what I did, as well as part #s. Yours may be different. Grease, grease gun, and packing tool are your choice. This is just what I used.
Outer bearing: L44649 (bought at NAPA)
Inner bearing: L68149 (bought at NAPA)Grease Seal: SKF 17146 (bought at NAPA)
Bearing Packer (not required, can repack by hand): Evercraft 776-9028 (bought at NAPA)
Grease - I used Moly Graph Grease available at NAPA and Harbor Freight in 3 oz tubes. Used for mini grease gun.
3 Oz. Mini Grease Gun with Cartridge - Harbor Freight
Repacking wheel Bearings on Parkliner (2014)
- Loosen lug nuts
- Jack up trailer
- Put jack under 3" metal frame, not under axle
- Put jack stand under metal frame, not axle
- Remove tire
- Remove dust cap
- Might be able to pry off with screw driver
- Might be able to get off with channel pliers (I used channel pliers and lightly tapped with hammer)
- Remove castle nut (looks like a castle)
- On my Parkliner, there is a tang washer holding it in place
- Clean castle nut as good as you can.
- You will see a tab from the tang washer bent over the castle nut holding it in place
- Using a screw driver, pry the tab up as far as you can
- Unscrew the castle nut - you may need to keep prying the tab up as you go
- Remove drum (hub). (Either remove outer bearing first or hold with hand)
- Clean axle and put a little grease on. (You could do later if you wish)
- Remove washer and outer bearing
- Remove grease seal (rear of drum by prying it off)
- Put end of punch under the edge of the seal and tap with hammer.
- Or put one jaw of the channel pliers under the seal and then pry it off. This worked much better for me. You could probably do the same with a hammer - like pulling a nail.
- Remove inner bearing
- Clean out old grease
- Check the race inside the drum. The race is what holds the bearing inside the drum.
- Make sure it is not scratched or pitted. If it is, replace.
- Clean everything - bearings, washers, nuts (paint thinner, mineral oil, brake cleaner, etc)
- Inspect bearings - scratched, pitted, discolored, damaged in any way
- If damaged, replace
- If not damaged, repack with grease. This is where I used the bearing packer tool. Don't mix grease.
- Put some grease inside drum
- Install inner bearing (small end of cone first)
- Install grease fitting
- Line it up properly
- Place a piece of 2x4 over the fitting and tap with hammer until it is flush with drum
- Install outer bearing (some people prefer to wait until drum is reinstalled)
- Put washers on
- Tang washer closest to bearing - make sure tabs pointing out
- Then flat washer
- Screw on castle nut
- Hand tight plus a little
- Back off about 1 castle point
- Bend one tab of tang washer down to lock castle nut
- Spin wheel - it should spin freely for several turns. If not, adjust.
- Put wheel on and hand tighten lug nuts
- Lower trailer, tighten lug nuts, remove jack stand.
- Use grease gun to fill hub with grease. Make sure you use same type of grease.
- Connect grease gun to ez-lube zerk fitting.
- Keep pumping until grease starts to come out from behind castle nut. I think it was about 5 oz.
- Wipe off all extra grease
- Reinstall dust cap - tap with hammer
- Repeat for other wheel
