Spare tire hoist rusted and won’t lower tire ?

[Tim Herald]

Per above title - I can’t get rusted hoist to lower and remove the old dry-rotted tire. Any suggestions on how to get that all out/off? If there is a way to cut it all off, I am good with it. I am going to eventually get a rear carrier. Wasted weight of old tire and wheel.

Have you gone nuts with a can of penetrating oil on it? Thats probably step 1.

With the tire in place you are limited to your options. I would attempt to take a cutoff wheel to the part of the hoist that goes through the wheel and holds it to the frame. The system has a chain that attaches to a metal fly that passes through the wheel center and hold in place. on the bottom portion of the metal fly there should be a spring and cap that add tension to the fly when against the wheel. If you cut the shaft going through the spring to the cap it should release the metal fly and henceforth the wheel. After that you can either remove the hardware or cut it out (like the cancer it is).

IIRC not all the bolts for the hoist frame assembly are accessible with the tire in place. IIRC @magavilla was doing some rust repair and removed his spare tire mount, he might be able to chime in on how it is mounted.

Goes without saying but if you opt to cut the pass through portion of the mount, please support the tire so it doesn't drop on your head.

Do what Malleus is saying below. I thought there were two bolts behind the tire but I was wrong.

This really isn't as hard as some are making it sound; support the tire and remove the (3) bolts (on both sides) connecting the tire support crossmember to the frame rails. You can then lower the entire assembly and do with it what you want...without having to futz around with it over your head.

And there is a kit floating around out there to raise the spare tire and specifically lift the front end to get it behind the rear axle better. It levels out the spare. So, those L brackets that hold the spare tire crossmember to the frame are not needed if you do that mod. And if you off-road your vehicle you should do that mod. I got my kit from Land Tank back in the day, or maybe Wits' End.

Thread '80 Series Tire Leveling Kit'

Jan 28, 2011

Due to the encouragement of several Mudder's, I've built a kit to level out the spare tire under in the 80 series LC.

With a stock vehicle this mod levels the tire out and moves the front of the spare tire further from the ground. There is a support rod under the aluminum tread plate on the rear bumper that sets the height of the rear portion of the spare tire. If you do a body lift and your rear bumper supports raising this rod, you can raise the back of the spare tire and gain additional clearance. The slotted holes in the brackets accommodate BL's from 0 to 1.5 inches.

The benefit...

In any case, I'd recommend reinstalling the crossmember after you remove the tire; it's sort of a structural part.

Yea I didn’t find it hard at all. I was able to get the spare off - which if the nuts are rust I’d leave it in place and cut the whole thing from the frame. Mine did come apart with the airgun tho - no crazy issues

As you can see, the spare is held by a chain - which I’d just cut with a grinder while supporting the wheel - or staying out the way. Once the spare is out you’d get access the the bolts that hold it in place.

Yes but gonna do it a few days in a row

Don't waste your time w/ the rusted hoist. Just unbolt the mounting plate and take the tire and hoist out with it.

Once it's all down on the ground you'll see the hoist is a simple mechanism, might clean up enough so you can reuse it. Definitly soak the bolts
with penetrating oil a few times before starting.

FWIW the WD40 Specialist Penetrating oil with the long flexible metal spray tube helps get to out-of-the-way fasteners, easy
to bend the straw up and over obstacles then spray down from above.

Wet it, not just soak it with Pb blaster for a couple of days, it will became loose.
