Wheel bearings

Fellow Jayco owners. A quick question about wheel bearing grease. My 2018 Pinnacle is 9 months old, and has been pulled locally camping for about 1500 miles. We are going to Branson in a couple days. Do you think I need to add grease, or leave it alone? Secondly, I understand it has Dexter axles , and that they use Lithium Complex grease . If I do add grease, can I use any good Lithiumcomplex grease rated for bearings? Your thoughts on this matter will certainly be appreciated.

I never add grease, if you do and the seals blow. The dealer,Lippert, and Jayco will blame it on you.We have 4 blown seals on our 2016 Eagle guess what! They are replaced under warranty. I would guess Lippert over packed then from the factory! Recently sold a 1999 Camary 228000 miles never added drop of grease. I realize there are many who would disagree to each his own!Thanks

Myself I would leave it alone, but if you and have the EZ-lube system be sure to turn the wheel when pumping grease. I do mine every three years. On the semi-trailers they have a mileage chart. It seems RV axle manufactures try to cover their liability, by setting a date or mileage limit.

If dexter packed them correctly, your fine. I probably had 15+K miles before I repacked them.

The key is make sure to use the same type of grease, if you pump it in. Personally I like to repack by hamd. This way you can inspect everything.

Thanks guys. I was leaning to leave it alone and repack them after this camping season , using Dexter grease. That way they canít say we used the wrong grease. After your responses, thatís the way I will proceed. Thanks again for your input.

On my prior TT the schedule was 12 months or 12,000 miles. I can understand the 12,000 miles but the 12 months never made sense to me. I had the TT for six years and put 7,800 miles on it and never repacked the bearings.

To me, the year/month thing doesn't matter.
I repack after the first year, just to make sure they were done right at the factory. Most times they were not....
Lucas Red N' Tacky is your friend....
Never use that "EZ Lube" fitting unless you want blown seals, and a mess.
Pull, Inspect, Repack, Replace seals.
Then every 12-15,000 miles, do it again.

I am not a fan of mixing grease types in wheel bearings especially. If you don't know what is in there wait and break them down and repack. I like the idea of repacking, inspecting, and cleaning every 10,000-15,000 miles. It is not a hard job to do and is one less thing to worry about while traveling.

I am in the middle of doing mine now. Unit has 10,000 miles on it and is 1.5 years old. They have not been done since the factory. From the looks of the grease it was time. The grease was not holding its shape good, what I call getting a little "runny", and some was weeping out of the dust caps. The hubs already had the double lip seals on them so I had no grease contamination on the breaks. Good thing I went through them because on my rear left, the back shoe was warn down to nothing, but all the others were worn evenly. Got the replacement breaks (for the rear left and right) in today so the back two wheels will go back on so I can hit the road this weekend.

My axles call for Lithium NLGI #2 so I am using Lucas X-TRA Heavy Duty Grease: https://lucasoil.com/products/grease...vy-duty-grease

Attached are some pictures of the worn break shoe.

Jason,

Thanks for the info. Iíve decided to do just that. Make the trip as is, and disassemble and repack this fall. I too am nervous about adding grease , and possibly damaging the seal. I also like the idea of being able to look at everything. Thanks for your input.
