body tub shims

Do these jeeps have shims under the tubs? I found a hunk of treated wood between the underside of my tub and the frame. I assume this was 'aftermarket', but are there normally some kind of block shims or just rubber mounts?

 

I used conveyor belt that I cut in squares between the frame and body.

 

This is like 5/4 decking or something pretty thick. So, I guess the answer is 'no'?

 

Any chance what you are looking at is from inside the hat sections, and the lower portion of the hat has rusted away??

 

From the factory many if not all had 1/2" thick pieces of cut up tire tread. That's what Pete had.

 

The rectangular flaps of tire with a large circular hole in the middle even had a Jeep PN, like 6xxxxx. They came in at least two thicknesses, each with different PNs.

AFAIK wood was only used as a hat channel filler, and was not a service part.

 

Oh, man, well, here's what I've discovered. The aforementioned piece of wood (just behind the right-front wheel, directly below the cowl):



On the opposite side, there is nothing and the tub is just sitting on the frame. Might explain why the pedals don't line up real well (that and they are loose as a goose).

Halfway back, under the "step" up to the rear floor, there seems to be some rubber pads on both sides that look right. However, in none of these locations is there a bolt of any kind. In fact, the only tub bolts I can find are in the rear where the frame arches up over the wheels. Looks like there's some pads there, too.

I'm assuming there's supposed to be more than two bolts holding the tub on, right? Sheesh, what a mess.

 

Your steel hat channel has rusted away. The wooden blocks were once inside the hat channel to act as a reinforcement.

 

Not in that area farther back in the hat channel there was oak inside. It's common for the outside of the channel to rot away and expose the wood. The support shown is under the cowl/firewall/floorboard area and didn't use wood

 

I am fairly sure that my 1965 CJ5 had a wood insert there when I replaced the hat channel.

 

To me that looks like someones atempt to make a cheap body mount. I have found similar things under past jeeps as well.
There was wood in the chanels but that dosent look like one to me, and the stacked rubber towards the back doesnt either.
Many people have probably owned and done many things to these jeeps over the years. Part of owning one is redoing many of the thing PO have done to them. I always replace the wooden and rubber body mount fixes with some type of better mount with bolts. The jeep I have now had some metal squares between the frame and body, took them out and replaced. Didn't even have a mount where you peice of wood is. I do now.

 

So, knowing that this is years of cobbled together mess, where were the actual bolts and rubber mounts from the factory?

 

On my 68 cj5 the larger sections of hat channel themselves did not contain any wood. However the 2 pcs that ran forward to the firewall each contain rotted wood. Also found wood behind the support for the spare tire mount in the passenger side wheel well. When I replaced the hat channels I drilled holes about every 4-6 inches so any water could now drain. Also painted the inside of the channels w/por15.
