On that big cross shaft, the joints are adjustable. You have to unscrew the center tube to access great big cross heads internally. Remove the cotter key, and tighten by inserting a tool into the cross.

This next comment is pure speculation, but perhaps worth looking into. The DANA IFS 84 suspension was made in Spain primarily aimed at the Euro bus and truck market. Replacement tie rod ends and drag link ends have been hard to obtain. I do not know if the taper used on Metric suspension parts is the same taper as used on SAE parts. My point being that if someone substituted a locally obtained rod end you MAY, and I say MAY, have a mismatch in tapers. That is pure speculation on my part
