    I don't know if this is common knowledge or not...

    I recently had to change the U-Joints in my '06 Suburban. They put like a nylon type of injection in the yoke and driveshaft ends to hold the U-Joints in. I beat on them until my impact socket was mushrooming, very frustrating. I figured I would just go after it with fire at that point. I grabbed a simple plumbing torch, using MAP gas and heated those suckers up, the nylon literally cam right out of the injection holes like a snake after expanding. Made things a boatload easier.

    It's one of those things you don't think of until it's too late. That's really the only way to get those stupid things out!!!!

    I discovered it on my own.. I noticed there were no retention clips so they must be factory and stuck after 20 yrs and decided to try heat... I got baby snakes and they came loose.. been doing it that way ever since.:innocent:

    You don't even need MAP gas. Any propane torch puts out plenty of heat to melt the plastic.
    Just be sure you are wearing face and arm protection before smacking it with a hammer because the melted plastic flies everywhere and is warm enough to be uncomfortable.

    Just be careful not to get it too hot as the plastic will then explode! A good friend of mine had it happen and got hit by hot burning plastic! A little heat goes a long way.

    What can also explode is if the rubber grease lip seals are still good, they blow out after you get enough heat into the joint. They sound like a gun going off, I have done this before and it is quite scary. To prevent this, I just pierce each boot with a pin before heating to get the plastic u joint retainers out from now onn.
