Rear end ratio

SOURCE: Will a rear end out of E350 Ford interchange with a Chevy 3500 dually

Is the c/k 3500 4 wheel drive?If it is 4WD,you must retain the same gear ratios for both front and rear axles,or the transfer case will be damaged.If it is 2 wheel drive,you can install any gear you like.I believe the Ford E350 rear axle is a Dana 70,as i have rebuilt 2 of that model,along with Dana 60's.The Ford unit likely will not be a bolt in.It will probably require professionally welding new mount brackets on the Ford axle housing.The width needs to be measured from inside the brake backing plate to the other brake backing plate to see if it will physically fit.Good luck.

If you have drums on the rer yes you do have to remove the axle its simple though you unbolt the 6-8 bolts on the end of the axle then it just simply slides out thats it there mite be some resistance but there isnt anything else holding it in. and you dont have to worry about putting it back into the same spot eather just slide it back in and line up the drum.
