    Hey Steve check this link out. It's probably the most comprehensive desciption of a ring and pinion swap.

    Good Info but would you attempt it?
    I also have a PowerLock for the front so with all this new harware is it worth the risk or just drop the 500 bones and move on to the next project...............

    I might attempt it in the future. I would get all the tools I needed first though. It is a little intimidating though. I like learning how to fix ANY part of my truck. I recently had my rear 14 bolt completely apart and it was pretty cool, but I didn't have to set the pinion depth and all that.
    My truck is a daily driver too so that may affect my decision when the time comes.[​IMG]

    check these guys out:http://www.ring-pinion.com/ enough in their kit to do one full differential. It comes with pretty good instructions, with illustrations. I used that when I changed the 8.5" carrier in my car. There are many tools that are recommended by many people, but aren't necessary. If you ask me, a heavy, WOOD handled hammer (for beating on the carrier with the wood end) torque wrench, dial indicator. and their kit should be about all you need. I may have missed a few things, but really the axles aren't that complex. It's the pattern that takes awhile to get right.

    Go for it, I say[​IMG]. I tried it and was glad I did. In addition to the tools listed before my post, a shop press is required. You wanted one of those anyway, right[​IMG]. I wasn't quite sure if I got the pattern right, so I took the carrier and pinion with the gear mark compound on it, to a well known shop. They told me it was good, and I have run them in my shortbed for 3 years now. Good luck....

    Burt, Im looking at the same thing. I got the video from Richmond gear, adn it looks straight forward. Plus my uncle has been a Gm mech for 30 years adn he says as long as you have good instruction, its not rocket science. Im starting mine around Febuary, after I get the tools and the parts purchased. Is this the pat on the back you were looking for&gt; Besides, you have a welder now, you can fix anything!!!

    I miss my Ex, but my aim is getting better!

    It may be in the same ball park for cost to just swap the whole axles. This is especially good if you really wanted bigger axles anway. Plus, if you would pay someone to set up your gears, but you would swap the axles yourself, the axle swap becomes cheaper. You may be able to get a few bones for your old axles anyway, assuming that they are still in good working order.

    I swapped mine out last summer. Its not that difficult, the main thing is that you have to realize that right from the start that you are going to be taking it apart and putting it together many times. I kinda got rammy and impatient so I put it together and told myself it was close enough after the 5th time taking it apart, now it is making a little bit of a howl when i hit about 70 kph. Im not real worried, a swap to heavier axles is in the plans, but I should have just drove the car for another few days and did it right... now all I can do is pass on my vast (haha) knowledge of it to others!

    Good luck
