Place to Jack Up to Grease Wheel Bearings

I need to grease my wheel bearings and check for any play on the wheels that could indicate wheel bearing wear. Is it okay to put a jack under the U clamps on the leaf spring assembly on the axle to jack up each wheel one at a time? I don't want to risk bending and axle and on these independent leaf spring suspension TT's backing one wheel up on leveling blocks to get the other wheel off the ground doesn't work. I just want to spin the tire as I grease a couple of shots and check for any play that could indicate wheel bearing wear. I have a small floor jack I can use. I have a 2018 25RKSL Aerolite and have had really good luck with it. No problems whatsoever and have owned it about a year and a half. Use it quite a bit but only make very short trips. First one I have ever owned. Thank you for your input.

The old car rule was always as close to the wheel as possible. So the u-clamps are probably a good choice. Only other thing I would add is make sure you are on absolutely level ground and only do one axle at a time.


Stay safe.

I agree. Be sure you have chocks forward and reverse.

Donít t Jack axle

According to the manual for myAspen Trail (yes I read it), the jack goes on the trailer frame and not the axles. A bottle jack and two jack stands are also recommended.

I have always jacked under the U clamps. I have never thought lifting one side of the trailer with a bottle jack on the frame was a good idea either. That is alot of weight and stress to put in one small portion of the frame to lift one side of the trailer. That said if you do decide to lift at the frame I would use a 12" 4x4 block between the frame and jack.

You should pull your wheels, remove the grease seal, clean the bearings, repack with wheel bearing grease, new seals. Tighten axle nut with proper tension and new cotter pin. Good time to inspect brakes and magnet..

I rarely deal in absolutes. But that manual could not be more wrong.
My trailer frame (2018 243 BHSL) is 22 inches off the ground. (your mileage may vary) My axles are not even 12 inches off the ground. Personally, being a shade tree mechanic of some repute. I have the proper jacks and stands to jack that far up. But you need more than 22 inches of lift. I imagine it would take another 6 + inches to get the wheel off the ground due to the slack in the suspension. If you ever do it that way. stand behind your trailer and enjoy the view. YIKES!



Jacking under the axle, your wheel comes off the ground in an inch or so of jacking. Using proper jack stands and VOILA! Your up and secure with only a couple of inches of lift.



In addition jacking under the frame will start to tear up the under belly cover. We don't need to add more problems.



Just my unrestrained opinion.

This is why wood blocks are recommended. Neither the RV mfr nor the axle mfr recommend jacking on the axle and for the same reason you give....thatís alot of weight ine the axle and it could do damage a number of wAys.

Iím certainly no expert, but when my choices are: following the directions of the manufacturer laid out in the manuals or following the advice of someone on the internet.....

I hear you but still have to disagree with the manufacturer.


Jacking a couple of inches on the shackle is a lot less stress and a lot less dangerous. The shackle is the exact same place where the weight of the trailer is under normal operation. No different. So where is the jeopardy?


How many 4x4 blocks does it take to get your jack high enough to get your wheel off of the ground? How high does the frame have to go to get the tire and inch off the ground??

Agreed. Anyone ever notice the manufacturer doesnít give you a jack for your TT? Spare tire? Yes! Jack and related necessities? You are on your own!
