I wanted to know who does what to their trailer for maintenance. and how often you check your trailers. I have a dual axle flat deck car hauler that has 2 axles.This is my first trailer that I've owned. I do the normal things like: check the tires, brakes, grease the wheel bearings. I was told trailer tires dont need to be rotated or balanced. I didnt rotate or balance the tires on my trailer and the cupped up very badly. I just want to know if anyone balances or rotates the tires,

 

I have the Dexter EZ-Lube axles on the camping trailer. I strip them and repack the bearings every other year. On the off year they get a few shots of grease (same grease as used in the repack.)
I have one corner that wears on the outside so I rotate the tires every year.
Having worked in a tire shop, if you balance the tires they should be balanced with a hub-centric adapter. A lot of trailer wheels have off-center center holes. Me? I don't bother balancing them.
Brakes get checked for function every year. Jack up a wheel, spin it, and pull the break-away pin. It should stop.
I replaced the tires last year. They weren't worn out but were severely weather checked and cracked.
The lights get checked every trip. And I manually pull the brake controller lever to be sure the trailer brakes work every time I go out.

 

I've had a lot of problems with the electric brakes. Once a wire broke to one side, so I only had one brake (single axle trailer). This got me in the habit of checking the drum temps when travelling.

So now, at most stops, I walk around and check out the trailer and touch each drum to be sure each one is the same hot/warm.

Then I started noticing that one drum wasn't getting as warm as the other. Adjusting the brakes didn't help, so I opened it up and found grease everywhere and a leaky grease seal. It was so bad that I just replaced the whole brake set with self-adjusting ones.

So no more annual brake adjustments.

Bearings regreased every 1-2 years. But really wish the axles had sealed, never-lube bearings like our trucks.

Basically the running gear under my trailer is pretty primitive compared to the truck.

Wheels came balanced from the factory, so will keep on doing that. Tires are going to be replaced after 5 years as a blow-out could take most of my outside plumbing at the same time.
