The Beige Jimmy

Sunday morning the kid was being an annoying older brother, pestering his sister and her girl friend. Instead of blowing up and sending him to his room like I might have in the past, I asked him if he wanted to drop the rear end out of the Jimmy. He leapt at the opportunity.

I had him break the lug nuts loose, put the jack stands into position, remove the u-bolt nuts, and disconnect the driveshaft. I did the rest of the disconnecting (parking brake cable and brake hoses), but they came apart slicker than snot because remember, I just installed all this like 2 years ago and everything was still in good shape. The brake hoses were the easiest fittings to loosen this time, while last time they gave me the most trouble.

So we got it dropped in short order, he stayed out of trouble, my stress level stayed low, and we grew closer together laying under this old beast.

Good times.

Next up: swap these brakes onto the new rear end, replace gear oil and gasket, scuff up, repaint, and reinstall.

This time, I'm not going to put it back on the road until I get my new 3.42 front axle under it as well. No more mismatched gears this year! (I've been saying that for 4 years)

That’s great. I always try to get my girls to help but that only last about ten seconds.
 
I've been putting in work, so here are some updates.

Last weekend it was finally dry enough to work in the driveway, so I got to work swapping the good brakes from the bad black axle to the new rusty one. 1000018587.jpg

Gotta take these shiny parts off of here:

And put them on here, after I take off these old dirty parts:

After a while I noticed the old (black) drum backing plate was a larger diameter than the new (rusty, yes I know it seems counterintuitive) one.

Hmmmm...

Would this be a problem? Stay tuned to find out!

While the drums themselves were identical diameter, it became clear that just the backing plate was different. 1000018594.jpg

This axle is from a 1990 K5 and the backing plate lip matches the diameter of the back of the drum.

This is from a 1984 K10 and the backing plate has a smaller diameter than the back of the drum.
This photo shows one of the reasons why I'm swapping brake parts over (broken piece of the drum)

All else being the same, I decided it was good to go. I reassembled the guts with the help of several kinda sorta helpful youtube videos and eventually I got it figured out. Much cursing was involved.

I rattle bombed it black and let it dry. I had a busy week at work, so a week went by before I could attempt an install today.

Fortunately when I bought these zero rate 1" blocks 2 years ago, I figured I'd get the 14" long U-bolts instead of the 10" offering. Silly me, these are way too long.

Now I've ordered the 10" U-bolts from ORD and they should be here by next weekend.
