the cable lowers all the way through the tire and makes it to the ground?
The tire must be stuck on something, try to get up under there and see whats going on.

hope you figure it out.

Happy trails.

Yes. The spare tire is located under the bed in the rear of the vehicle. You have to use the handle of the jack to lower it down. There is a place in the bumper next to the License plate that you stick the jack handle in to lower the tire down.
Please RATE! Click the 4 thumbs ups!!! Thanks! Have a GREAT DAY!

The spare tire support cable has an additional safety mechanism prevents the spare tire from falling onto the road should the cable break. This mechanism often gets filled up with road grit and won't release properly when you try and lower the spare. If your spare comes down a few inches then won't go any further then this is your problem. There should be some tin brackets included with your jack that are supposed to hold the spare tire up slightly off of the ground to allow some slack in the cable which usually [but not always] will allow the stuck mechanism to come loose. There is a more detailed description of this procedure in the owners manual. IF the spare won't move at all or the mechanism just won't release no matter what you do then you may have to have the entire spare support mechanism replaced.

You must unwind (counter clockwise) with the tire tools that come with the truck, sometimes the cable gets jammed on the spool it may take 2 people to get it loose,one must pull down on the spare while the other unwinds it. Try not to get under the tire as it is heavy.

CAN YOU PULL ON THE TIRE WHILE YOU LOWER IT. IT MIGHT BE GETTING CAUGTH UP IN THE CABLE HOUSING

there should be a hole for a crank either next to the licence plate or between the bumper and the bed

may need to replace shocks or leaf springs.

try junk yards .com
or if you no anyone with a garage you can make one
or just cut the cable and put the spare in the bed
