Rear End Locked Up

Just took my truck through a car wash, pulled out and went to the next building over for some Chick-fil-a. Parked the truck and when I went to leave I couldn't back out. Something is locked up. This happened once before after washing my truck and my theory is maybe the rear drums are locking up? Last time i had it towed and while it was sliding off the flatbed it freed itself up. I didn't realize it until now because the truck has been fine ever since the last time it happened. Anyone else ever come across this?

 

Just two weeks ago I went through a lot of mud and some water crossings. Rear drums locked even when I put it in 4lo. Rock it between D and R and keep pressing brakes is what helped me. Next choice smack the drums with a hammer a few times

 

I hate drums

 

Put it in 4lo and rocked back and forth, did the trick.

 

How long did it take, it took me 10 minutes or so

 

I was being pretty agressive, so only about 2 minutes lol

 

Haha I would have but didn't know what the fuck was going on when it happend. First I thought I fucked up gears

 

If you had the brakes really hot and then put water on them they can fuse like that. It happens to disk brakes too.

 

I was pretty cautious the first time, I thought the same thing about it being a diff problem. That's why I had it towed.

 

When that has happened I just get out and kick the tires a few times and it frees itself. You'll hear the pop when it breaks free. Never had to put it in 4lo to free them.

 

The hammer helps with my aggression

 

Maybe you're E brake cables are toast, I had them go on my '06 and they fried my brand new brakes and one of my brand new $110 brake drums. They are exposed and would easily get wet during a car wash. When the E brake cables rust up, they can lock the brakes on.
