Re: [FWDLK] Swapping rear end gears

[William Huff <whuff@xxxxxxxxxx>]

The way I read the message all he needs to do is change the ring gear
over to the sure grip and install it back into the existing pumpkin with
new side bearings.  If the rear end was good to begin with, then no
other adjustments are needed except backlash.  I would replace the
pinion seal as well.  I have done this operation several times in
the past with good results and no special tools needed other than a dial
indicator.

Bottom line is that you need special tools, dial indicators, and much experiance to get it right. NOT for the novice, you can do it, but it will soon fail. Pay the man to  do it right. Find a good rearend man, it's worht it.

Of course, that would most likely be the "easiest" thing to do....but according to this website http://www.planethoustonamx.com/main/chrysler_8_34_rearends.htm it is apparently possible to swap out just the ring and pinion, thereby retaining the capability of the sure-grip rear end.

 

Now having read this myself, I am wondering as to the actual feasibility of making this switch....assuming (hate that word, :), that I can locate a mechanic knowledgeable in such a swap that can deal with all the various settings which need to be done.....

 

....since I KNOW the sure-grip is in good functioning condition, and am not all that sure of the non-sure grip carrier assy.  I mean, it certainly LOOKS ok and there are no obvious chipped teeth on any of the gears......it's just that one never knows until it's in place.

You will DO much better swapping the whole center section I believe!
