How To Change The Cab Mount Isolators? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I noticed while I was on vacation that My camper looked crooked over the cab of my truck. Well, since the bed is bolted directly to the frame this only led me to think that the cab was leaning a bit. Sure enough, the pass side rear rubber was collapsed about one-half inch. Now then, can these be replaced without removing the cab from the frame?

Yes, if you can get the bolts out without breaking them off...

I will soak them with PB Blaster for a couple of days then do one side at a time.

Loosen the opposite side, remove all the bolts on the side you're working on. Jack up with a 2x4 across the entire cab. Replace and leave 'em loose.

Do the other side and tighten em all down.

Sounds easy. Thanx!

I just did this on my truck and it took about 2 hours. It's really easy. Most of my time was spent messing with a bottle jack and 4x4's as my floor jack is "jacked". Don't forget to loosen the radiator support mounts before you jack up the cab.

the radiator supports came in the kit I bought. So those got done, too

This may be a dump question, but do u need to loosen the radiator support bolts if you only want to change out the cab mounts?

Thanks.

Thanks, I noticed that which is why I asked. I need to replace one or two (temporary fix) cab mounts and was wondering if it is necessary to loosen the radiator support bolts to do so. I wasn't sure he mentioned it in the post as replacing them at the same time, or to loosen them to make changing of the cab mounts easier (and not screw up anything up front).

I'd loosen every mount bolted to the cab and fenders, to give you enough clearance. Also, don't wimp out on us now. Do them all :p
