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.

I have a 98 Ford E150 conv. van need to replace complete rear end need to figure out which one I have and what yr will interchange and if a truck rear end work or only a van


Hello Brenda...you will find some identifying information on the actual real axle casing. Stamped numbers, I.D. tag or you can search your VIN (Vehicle Identification Number) or make, model year and series on the internet to see what options were available for rear end gearing ratio's.

Yes you should stick with a similar or identical rear end to ensure proper mounting bracket alignment and gear ratio choices. Dana Model 60, 70 & 80 Axles are not internally identical.

Looks like the standard differential carrier for the E150 is a 8.8" (*10 bolt). Standard, Includes Spider gears, 31 spline, 7/8" shaft.

* Ten Bolt - The rear end cover plate contains 10 mounting plate bolt holes.

Rear end ratio


Being that it is a one ton I would expect it to ride rough. It is made for hauling a heavy load. If you want to improve ride quality you will loose hauling capacity unless you spend the money for an air ride suspension system.

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.

Hello, the rear axel seal on my Dodge Ram Dually


is not that bad just take the tires off then take the diff cover off take the drum or disc off on some truck there is four bolts on the end of the axle tube that you have to remove to get the axle out. but, if you look insider the diff and see two clips that look like a c ust take the bar that runs threw the middle of the diff and holds the spider gears inplace and keeps the axle from moving back and forth out and push the axles in and remove the clips then pull the axle out and rip the sear out and install the new one.
