ERA Chas: No problem now, although the steering wheel moving around at high speed can be a bit troublesome
at high speed. The bushing wasn't worn, but the press in the housing that retained it was lost. Once fixed in place with Loctite the bushing stays in place and the steering shaft has virtually no play, so all is OK.
On another note, the 3--4 shift is difficult, however all others are smooth . . . ZF transaxle is used. Once the transaxle is warm, the shift is a bit easier, but still a little difficult. I seems like the synchros are ok, so I suspect the problem is with shift likage adjustment. Have you experienced any such problem? If so, got any suggestions on a cure?
