Bearing Buddies for trailers
 
Afternoon all,

Is there any difference in the quality of the bearing buddies from Cabela's versus those from Harbor Freight/Wal-Mart? I'd rather not order if I can pick them up locally.

Jtrask,

As long as they fit tight, they will work fine. It is nice to have the plastic caps also.

good luck

Dan

I will post a few pictures later

Keep in mind they ONLY put a bit of grease on the outer bearing as it cant travel across the spindle to the inner bearing which is most subject to water intrusion from a leaking inner seal

The newer drilled axels that have a grease passage to the inner bearing are vastly better

Bearing Buddies are a poor excuse for proper maintainance and I would not waste money on them!...Dale

This is not true. The idea is to pack the entire spindle volume too with grease, and it will then move continuously through the outside bearing, along the spindle, and through the inner bearing.

Not strictly true, Mark - it really isn't a good idea to fill the entire spindle with grease. If you do this, with nowhere else to go, the grease gets forced into places it shouldn't ever get to - like the brake shoes.

(Don't ask me how I know.. :rolleyes:)

Not true either.. Bearing buddies allow the grease to expand and contract as the wheel/axles gets heated up and rapidly cooled down (particularly on launching the boat after a long drive!) preventing water getting sucked into the bearing and subsequent bearing failure...

I'd consider them essential myself.

Hehe.. depends entirely on how much grease you put in, I suppose. :cool: :)

Why not pick up a set the highways are littered with them!... Dale

Too true!.. another good example of what can happen if you overfill them. :)

As a matter of fact I am and expert :)

Stage three

They there always leak the rear sealing area is mild steel and fails even in freshwater

http://im1.shutterfly.com/media/47b7...D550/ry%3D400/

They invented SS speedy sleeves to fix issues as it now has a surface a seal can stay alive on and NOT rust ASAP

http://im1.shutterfly.com/media/47b7...D550/ry%3D400/

They can be driven on over a sealer with some caution and primitive tools


http://im1.shutterfly.com/media/47b7...D550/ry%3D400/

They leave you with a PERFECT SEALING area that will NOT leak

Smart people still spend the two hours once a year to check

http://im1.shutterfly.com/media/47b7...D550/ry%3D400/

And travel with a road kit


The bore area were the buddy installs has a primitive size tolerance on a good day and depending on the hub they are between a hand fit and a sledgehammer

They do allow for a bit of thermal expansion BUT still only lube the outer bearing which already has plenty of grease
