The suspension was very reliable. I loved the setup except for the fact that I couldn't keep axle joints in it... and when they went they took the shafts with them. I figured that if I was going to spend a grand (or two) on high grade joints and shafts I would rather just put that money toward a d60 and run stock parts until I outgrow them. So far in 6 months I've put more trail miles (and harder ones) on my 60 (with zero joint failures) than I did in a year on the 44 (with about 10 joint failures). There are some that think I may have not had my steering stops set in far enough and was over steering/binding the axle joints... :o that might be so. either way, I had a lot of these
Shoot me a PM with your email and I'll send you some pictures. Yeah, I used the ford radius arm brackets with some james duff poly bushings to correct the pinion angle.
Here is was it looked like when I was modifying the arms:
And even without a "wristed" arm flex was not an issue.
