RT 622 trail arm replacement

[cptjam]

Coming back from WI, SpyderAnn's trailer spit out all of her left side wheel bearings. It ruined the hub, axle, and tried to wear a hole in the wheelwell. The axle is welded to the trail arm, so, the whole assembly has to be replaced.
Step one: remove the cargo box body. I had hoped I could remove the trail arm by itself. Nope. So, 8 bolts, a ground strap and the wiring harness connector, and the chassis and box are far enough apart to get to the bolt that serves as an axle.
Then, remove axle, and press out the bearings. Press into new trail arm. Use anti seize. Then re install arm, shock, box body, hub, bearings, seal, cap and wheel.
Pix to follow, once I get done! Joe

For the price of these trailers and the service to the hubs is crazy ! BRP never hear of grease buddies . I travel with a spare hub in the trailer and when ever we stop for gas I check the hubs for heat. Who repacks bearing anymore ?

Good to know you're keeping busy. Sounds like a lot of work.

How many miles do you think the trailer has one it?

IIRC they use roller bearings instead of tried and true taper bearings on the trailers?

picture delay

Won't load pix.
Ann has 50K plus on that thing. Why it does not use a sealed wheel bearing is beyond me. The swingarm does, but not the wheel. Huge PIA to fix. No, you can not remove and replace with the body on. Impossible - they set the bolt that serves as the trailarm axle in from the inside out - body has to come off to slide it out!
I can try again later. :banghead:

Pretty certain you have it well under control. Consider that Murphy Browns trailer had issues eating tires. Supposedly it was a defective suspension arm.

Prior to closing it up, it ay not be a bad idea to verify the wheel alignments.

Simply a suggestion, not telling you what must be done.

Alignment

There is nothing to check. No adjustment, no way to do anything. I did check to make sure the axle is welded on at 90 degrees. It was. Should be ok, and as soon as Ann comes home, it will get a test drive!

Thanks!
#1 is removing the bearings from the old trail arm.
#2 shows where the trail arm mounts.
#3 shows how high the body has to be lifted to pull the trail arm axle, which goes from the inside out!
#4 shows the top of the bracket, which the lid mounts to. So, yes, the large lid comes off.
#5 shows the inner wheel well the tire tried to rub a hole through!
All fixed! Put new hubs on both sides, had a spare wheel and tire (old one is toast), and freshly packed wheel bearings.
I wonder why the trail arm has modern sealed bearings, and the wheels have old school bearings! Every 7500 miles, repack. I might change that to every 5000.
This repair cost over 500 bucks, plus lots of time. Special thanks to Ron and his grandkids, who helped me lower the body and place the bolts and rubber washers. Cheers!
