This is a picture of the old pad from my '08 on the left and the new pad on the right. As you can see, the old one is much heavier. You have to scroll down to post #8.


Now I know why jacks are punching through

They sent you the wrong pad. Mine had the thin metal from the start the new ones are reinforced different.
Here's the link with the different pads.

Thanks for all the thoughts. Called Equalizer. Told me there has been no recall and no real issues with the pads in a few years. I can order a new pad and bolt for about $55.

Asked about the power being out. Told me the assembly for the jacks is located in the passenger side bay, second from the rear. Checked the fuse there and it's good. Pulled the panel and all the connectors look good as well. Emergency brake is on. Hmmmmm.

The crucial part of the jack pad is where the hydraulic ram seats onto the pad. The contact area between the ram is a circular ring and very small in area. If for example a rear jack is supporting say 8500 lbs. and the ram's contact area is between 1 to 2 square inches; this means the rams pressure on this very small circular seating area may be 4,250 to 8,500 psi.

Now if the pad is cocked because of un-level ground, the psi increases on a portion of the contact area. That is why there is punch-through.

It doesn't matter that the pad may be 10 inches wide and 1/4 inch thick. What matters is the area and strength of the contact area. I believe there could be a better design to transfer the hydraulic ram's enormous pressure to the pad. - Hank

It sure isn't rocket science to fix a problem like this. Any competent welding shop could fix it in less than an hour.

As good a reason as there is. It's a simple equation that any first year engineering student would get. So why are we still having issues and why hasn't Equalizer fixed it.
I agree with OC you don't need an engineer a competent fabricator could do this easy.

I switched to the new pads about a year ago. Parked and leveled on asphalt about a month ago with some rear to front and side to side slope. Bent up one of the new pads pretty bad. Not sure the new design is all that great either.

My Legacy has the same pads, I punched through one a few months ago (totally my fault). Simple to remove with an impact, I straightened and welded up and bought a new one just to have on hand just in case.

key pad not working. I had the key pad not powering up. check fuses , if not fuses ,check for loose connecter on key pad mod,located in storage under rig. draw a x between front and rear tires and you will find it between frame rails. had it happen to me.

The new design has the same material for the pad itself the where the ram contacts it is much stronger.
