Where to place jack when changing tire

I have a 2018 315RST Crusader. Can someone please tell me the proper place to jack the unit without causing damage? My owners manual does not address this. Some say to place under axle near or on u-bolt and others say to place the jack against the frame. Any info would be appreciated.

Either place should be ok, just don't lift at the center of the axle. Which you use depends on the type of jack you are using, the terrain the jack is resting on and the amount of lift the jack has.

I'm no mechanic. I'm not even handy. So, take my advice for what you paid for it.

My take is that the axle tube is already supporting all of the weight at the U-bolts. So I jack between them or right next to them.



I really would like to have a "U" cradle made to straddle the U-bolt and curve up around the axle. But I haven't gotten around to asking anyone for it yet.

I also need to try out using my leveling system for this. Supposedly it's the easiest way!

I've had to change 2 tires on the side of the road over the years. I use the orange blocks that are stackable to make a " ramp" and then back onto or pull onto depending on the circumstances until the flat tire is suspended. Change then drive off ramp.

Great idea !
Last tire I raised the side of the trailer with the leveling system.

Where to place jack when changing tire

Best thing to do is get out your wood blocks and drive the trailer tires up on them and stabilize the RV and get the flat tire off the ground. Once you have it there, less jacking required. Stabilize the RV with stabilizing jacks if you don't have leveling jacks. Stabilizing jacks are not really made for lifting the RV. Then you can jack the RV up enough to get the inflated tire on.

Jacking a Trailer

I had built, a half round 4" long piece that mounts on the top of my bottle jack. It snugly fits the OD of the axle. Then I place it as close to the axle end as possible. To me, its much safer than placing the jack under a spring or other flat area.

Using the leveling ramps is definately the way to go in my opinion. No crawling under rig, Safe, easy. Only one experience but easier than any tire change that I have ever done on an auto.
