Rear 10.25" diff

Ok, i broke a yoke that attaches onto the diff. I thought i could just put a new one on. Then i realised it needed new pinoion berings. And todo that you gotta take the carrier apart. And I may as well replace the posi (the posi isnt really a posi anymore). So ive been thinking of replacing it with a locker. Is there any good ones, ive been thinking of a detroit locker. I plan on towing the boat in the summer and hitting the local strip for some races and daily driving. Any suggestions on what type of locker to get? Or tips on rebuilding a 10.25" rear axle

If you have never done it then i would recommend taking to a shop. There are special tools you need. There are shims to set backlash and check for a good pattern. The 10.25 is a heavy unit too. Good luck. If you need pinion bearning you might as well replace all of them while your in there. I had gears and bearings put in mine and it ran me 700 but i reused my posi.
