Ok, am getting myself ready for installing the new 5/8" pads on the motorhome. Had a couple of questions pertaining to what I see posted as the procedure for it. It looks like the new pads are turned 90 degrees in their installation as to how the old ones seem to be on the coach, where the length of them run in the direction of the steel frame. I know it appears that they are installed at a 90 to allow the SS screws to be placed. Is this ok to install this way? Was wondering about bearing pressure per square inch. Length wise along the frame rail would provide more bearing area per pad. Just wondered if this was any concern. Second question is the replacement of the frame tie down angle in the u-bracket. I understand making one leg of the angle longer but I guess I don't understand how you get the old one out and the new one in? Is it just unbolting it and slipping it out from the u-bolt and then doing the reverse for the new angle?
Thanks,
Tom

Tom,
Should you have the side step, be sure to loosen it as one can break the
step when lifting the body.

Had a couple of questions pertaining to what I see posted as the procedure for it. It looks like the new pads are turned 90 degrees in their installation as to how the old ones seem to be on the coach, where the length of them run in the direction of the steel frame. I know it appears that they are installed at a 90 to allow the SS screws to be placed. Is this ok to install this way? Was wondering about bearing pressure per square inch. the pads we used were much bigger than the original. They look as good today as when we put them in. Length wise along the frame rail would provide more bearing area per pad. Just wondered if this was any concern. Second question is the replacement of the frame tie down angle in the u-bracket. I understand making one leg of the angle longer but I guess I don't understand how you get the old one out and the new one in? Is it just unbolting it and slipping it out from the u-bolt and then doing the reverse for the new angle? The part bolted to the frame (the "J" bracket as I call it) when unbolted from the frame rail, just pulls out at the bottom and comes right out in your hand. Ezzy peezy.When you're ready to button up these side mounts, it's very easy to put the new pad in place before bolting the J bracket to the frame. IIRC, we used the old pads (4) because they were not at all squashed.
