    Can you replace the spider gears and shaft without removing the unit from the housing on a 7 1/4 open differential?

    I have read that to remove and replace the unit requires a case spreader tool. Is it possible to do it without?

    YOU DON'T REALLY NEED IT. JUST PRY IT OUT AND CAREFULLY TAP IT BACK IN.

    Got the parts in today and figured it would be a good time to tackle this job since it is raining. Pulled the Axel's and the differential. Got the Spider gears removed and the new ones installed with a New shaft. Everything cleaned up and ready to put back together tomorrow. Had to pry the unit out. Hope it goes back in the housing without any trouble. Now if I could get the pinion nut off. The nut is right hand thread right? IMAG0724.jpg IMAG0724.jpg

    I have never seen a case spreader for a 7 1/4 and didn't even know they existed or needed one until another thread on here in the last few days.

    Never heard of anyone using a spreader tool for the 71/4 differential but Chrysler listed one. Miller tool c-3721. Dana's used a different spreader. 8 1/4,8 3/4 and 9 1/4 don't require one. If you would like to look at the miller c-3721, do a eBay search. Back in the day miller sold the tool for 63.75, of course it's been discontinued for many years.
