I have 2 --1994 B350 vans one has 3600 lbs the other a parts van 4000 lbs front axels.. The spindles are twice or greater on the 4000 lbs . Im having problems finding the caliber mounts for my driver... Can I use the 4000lbs on my 3600 lbs by changing the spindles and other components needed.. Will the ball joints be the same ? Pitman arm ? Its cold in Manitoba...Thanks Unkelkennie

 

I'd go online to look for the part numbers for the different trucks ball joints. If they use the same part, yeah, they'll probably swap over. I wouldn't think they would as the design is different. However, you never know.

 

I already have looked online for part numbers..It looks like I have to change the lower control arms as well and all the steering .. Thanks ...
