Frame Cab Mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Palf70Step** · 12-14-2002, 05:13 PM

This maybe a strange question but here goes anyways. I'm wondering if it is possible to put new frame/cab mounts on with out removing the cab?

They look 32 years old, and since I replaceing the front end and bed mounts I thought it would be good to do these too. My thoughts are to loosen all four bolts, then use my two floor jacks to lift the cab enough to slip out the old and slide in the new. It seems to me it would work on paper, but not sure if I am undertaking a mess.

Since I moved the shift to the floor, I don't have to worry about linkages. I figure I am going to have to disconnect the steering column so it'll lift, and I'm guessing the clutch linkage.

Is there anything else that might not let it rise up an inch or so so I can change out the mounts?

When I do this I plan to have everything out of the interrior, seat/tank etc. Doors will still be in place though.

Am I insane (OK, besides the normal insanity) for trying to do it this way?

Thanks for the help folks.

Thats how I did mine with no problem except rusty bolts not wanting to come out. Dont forget to do the Rad support mounts.

Good Luck

Got them. That is why I wanted to do cab. New bed and rad support and mounts going in. figured cab should have them too.

Did mine last year, real easy. I had to cut all my bolts off. Used a jack and did one side at a time you do not have to lift much. Bought all new hardware from LMC. Have pics in the link(My 70GMC) in signature.

Once you remove the bolts, the cab only needs jacking an inch or so to allow removel and install of the new mounts. Keep in mind that there may be spacers between cab mount and rubber spacers to make the cab to frame level. I did not need to unbolt steering column, clutch linkage or anything. Even was able to leave the seat in but did have to remove the capeting (according to Mr. Obvious)! Huck

Thanks for the info folks. It seems I am jnot as crazy as I though, or we are all in the same nut house.

Huck..My seat will be out because I am going to redo the inside..rust coating paint and all for the final (??) assembly. That's why I was asking now. Figure most everything would be out of the way, what better time to do it.

When I did mine the bolts in the in the front floor pan were welded in. I had to take a dremel and cut it out.
