isolation pad installation

[tom geiger]

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

It won't improve her ride, but, it might improve yours.

Tom,
At the risk of getting flamed, please read my posting from Faye and Bert Curtis's site.

I know everyone says just put a jack under the cross-member and jack it up till you get room to stuff the new one in. My experience and my farmboy
mechanic tells me that jacking up a single cross-member will just bend the cross-member. You need jack the frame off the suspension and to lift the
whole body side, one side at a time using 3 or 4 jacks.

Just my experience , for what it's worth.
