Jacking up my 5er to R/R equalizers

[Calkidd]

I have a 2006 F37SP Sierra Sport TH. I am going to be replacing the equalizers and shackles. My dilemma is how to safely jack up one side and support the trailer in order to remove both wheels and do the work.

My first thought is to hook it up to the TV to keep the stress off of the landing gear. Have the wheels up on on blocks to minimize the distances the trailer will travel to get off the ground. I have a 20 ton pneumatic bottle jack, a 3 ton floor jack and two 6 ton jack stands.

What I don't know is how to go about getting both axles up far enough and supporting the trailer correctly and safely. Do I jack up one axle at a time and support the frame before moving on to the other axle? Where do I jack up the trailer and where can I support the trailer with the jack stands? Of course I am only doing one side at a time.

Thanks for any help.

What a great idea and I love HF! That's where my 6 ton jack stands came from originally.

I think I'll have to use a 2x4 on top of the stands. The frame near the axles are an I-beam sandwich below the frame of the trailer. The jack stands bend the lip of the I-beam up.

My harbor freight has 6 ton jack stands on sell for $34 and 3 ton for $21.

This is how I put my 10,000lb 5er on 4 jack stands to flip the axles.

I was able to lower the front of the 5er using the landing gear as far down as they would go. Then I put jack stands about 6 inches behind the rear axle. Next raise the front using the landing gear until the wheels lift off the ground. Then put another set of jack stands 6 inches in front of the front axle and lower the 5er onto the front jack stands. The 5er was suspended on the 4 jack stands, but the wheels were barely touching the ground and could be removed to give access to the axles.

For safety sake I added more jack stands behind and in front of the main jack stands because I happen to have 8 jack stands and figure more is better, but with the 4 six ton stands I do not think the extras were necessary.

That does make sense and It is a good point. I guess I will need to get another set of 6 ton jack stands. Even though the dry weight is 11K it seems like the trailer weights 20K.

So would it be better to hook up the trailer to the TV?

I purchased the Morryde upgrade wet bolt kit.

Believe me, attempting to do one side at a time is tough. What happens is everything goes out of alignment and trying to get the shackle bolts back in is not for the faint of heart. Your better off supporting the whole trailer, get all wheels off, then you can drop one axle at a time. Dont forget wet bolts and bronze bushings. If you have the plastic bushings they likely will already have failed.
