Hello, I have a 1991 e 350 ecoonline, the rear end is shot, can I used e250 rear end with the same springs, or must it be a 350 rear end. Also what about a e 150. As I look, what years should I search for, 1985-1991, or will othe years work. This is a bucket truck that I use on my own property, I would like the option of taking it on the road, but no a necessity. Can I cut the u bolts and leave the springs attached, or should I take out everything. Thanks, located in Wisconsin.

 

The 97+ 250 uses a semi-floating rear axle, I believe the earlier ones were both full-floating, might possibly be the same, but I'm not certain. I have replaced several rear ends, always cut the U-bolts and left the springs in, I would never put a 1/2 ton axle in place of a 3/4 or higher.

 

I think he wants to use a 3/4 ton rear end in a 1 ton chassis.

 

E250 uses a D60 semi floating axle while an E350 will have a D70 full floating axle. The D60 will bolt right in and work just fine but it doesn't have the same weight rating.

 

Thanks for the info, I wanted to know if I could use a 250 if I came across one,I currently do not own one. What about out of a truck?

 

Van is wider and the spring perches would be off, along with shock mounts.
