Check out the last paragraph, re: which proportioning valve should I use?

It says that either will work, but the YJ valve is cheaper

What does the proportioning valve do?

Assuming you're talking about the brake system...
The proportioning valve is on the rear brakes only when the vehicle has rear Drum Brakes.
What it does is limits the brake line pressure to the rear brakes during normal stopping. This way the rear brakes don't lock up and cause the vehicle to fish tail or spin.
When you press the brakes harder than normal, the proportioning valve opens more to allow more line pressure so you're able to stop faster.

How do i replace the passanger side window regulator on a 1983 cj

You will have to take the door panel off. Roll the window down/up about 1/2 way. Look at the channel were the bottom of the glass sits. There are most likely a couple of screws, 1 near each end. Loosen them up and remove the glass by holding on to it while lowering the assembly all the way (crank it down. Tilt one end up and lower the other. Glass should come out of the track. Reverse to replace the new glass.

We were wondering what kind of lube you put in a cj7 manual transmision

Usually 90 weight gear oil will do, they have new synthetics out now that run hot, and work better, but most transmissions never see an oil change or a drop of oil in their lives. I pulled the plug on my Toyota Land Crusher one day to check it, and nothing came out. Been running dry for years!

Replacing front shackle 1983 jeep cj7

Shackles are pretty straight forward. Remove the existing bolts, change the shackles and reverse the procedure to install. Good idea to change the bushings while you're in there if they are at all questionable. It's best to do this with the CJ in the air, supported on the frame and use a floor jack under the axle to lift/lower the spring in/out of the shackle, one side at a time.

Sounds like the clutch disc it sticking on the input shaft, or you don't have something correctly aligned in the clutch pressure plate. Or possibly the throwout bearing sticking.
