Need help with my rearend
I have a 71 5 lug rearend for leaf springs but my frame is a 70 with a 6 lug. i wanted to change axles shafts and make it 5 lug. i read some other post on this and there are some shafts that are different sizes. my question is if both housings are the same measurement can the shafts still be a different sizes.
another question how do you take the the axles out please HELP. THANKS JOHNNY |

Re: Need help with my rearend
If you measure backing plate to backing plate, and come up with the same number... then you are in luck.

Re: Need help with my rearend
If memory serves me right, you have to remove the gear housing plate & drain the oil. Then push inward on the axles and remove the "C" clips inside the gear housing. Then pull the axles out.....Reverse the procedure to install the other axles..

Re: Need help with my rearend
The 1970 6 lug rear end is the only one thats the same width as the 71/72.. so your axles will be a direct swap...
To do so you will need to remove the rear end cover and drain the 90wt.. try not to get any of it on your clothes, the smell never comes out!!.. you may have to rotate the carrier to find the little bolt that holds the pinion shaft.. remove it.. hopefully it will be whole.. they have a habbit of breaking.. it should be about 2 1/2 inches long.. it all goes well there, slide out the pinion shaft.. push in on your axle shafts and then you should be able to pull out the "C" clips.. or more likely they will fall out.. just reverse the procedure for installation.. |

Re: Need help with my rearend
Buy new seals while you're in there, and if you have the money, get synthetic gear oil....10 times better than the crap you'll be dumping out.

Re: Need help with my rearend
When you get things apart, check the axle shafts where they ride in the bearings. G.M.'s have a bad habit of eating up the shaft surface.(poor design) Can be repaired with offset bearing kits.
