Kind a silly question, but I very often have broken stuff when gon solo when being in doubt, so the question is that how do I properly jack my trailer up?

I have my X-Star sitting on the trailer and I would like to change the oil to the trailer wheel bearings.

The trailer is the MC tandem axle trailer and would like to know whether I can just put the jack under one of the axles and pump the thing up and do the work??? Or is this not the right location to place the jack?

Thanks for help!!:D

Why do you have to jack it up to change the oil in the bearings?

You have to turn the hub so the screw/setscrew hole will be on the bottom to drain, then turn the hub till the hole is on top so the new oil can be put in the hub, while the wheel/tire is off the ground. What are the chances that all 4 will be on the bottom at one time where he choses to do the work.
Jacking up each wheel at the spindle will the shortest route to get each wheel off the ground the quickest.

Stupid me, I didn't think of that.

You can jack the trailer up by placing the jack under one of the axles. You'll have to pull each wheel off in order to get to the drain plug. The center cap on the wheel covers it up.

Once you have the trailer jacekd up, make sure you are patient to let all the oil drain out. I just changed my hub oil and it took quite a while to drain all of it. I found that turning the hub each direction helped it drain quicker.

It also takes some patience to fill it back up. Its a slow process. Near the end, you'll spill more oil than you'll get in the hub. MC manual says to stick with it since you want max oil in the hub and as little air as possible.

That again does not jive with the instructions on the hub. It says on the hub cap that one should fill to the top of the "reliable" logo not all the way full:confused:

although my mc trailer is a single axle, it does not look sturdy enouth to support much weight. so, i place a 1-ft 2x4 laid flat on the frame near the wheel and jack from there. when i took my trailer in to have the bearings replaced and packed ($60) with boat on trailer, they blocked to avoid scratches and jacked on the frame near wheel they were working on. hope this helps.

A "2-Ton" jack stand under each axle should do the trick, working on one side of the trailer at a time. Yes, fill the oil up to the top of the logo on the cap - which amounts to about 2/3 full. You can buy 50W motor oil for the hubs at most NAPA or automotive places.

For filling the hubs, I found it extremely helpful to buy a $0.50 mustard or ketchup squeeze bottle. They have clear ones available at Wal-mart so you can see how much oil is in the bottle, etc. Fill up the squeeze bottle with oil, stick the pointy end into the fill hole and squeeze away until you have the proper level. Piece a cake. You will find the oil 'settles' as it moves through the bearings, so don't be surprised if you have to initially add more than you think.

Thanks everyone for your god feedback and advice!!!

I live in New Zealand, so no Walmart here, the best place for automotive parts and tools is Repco. They did not have that 50W motor oil, so went to a trucking parts store. They had it, but in 20 litre containers and the price was 400NZD = 260 US$, autch autch:mad:

So went and got the 80-90W gear oil and am just draining the right side hubs as we speak.

Job should be done in 10 minutes:)

Merry Christmas to you all!!!
