RD4 4G steering clutch gone?

An adjustment nut may have stripped and slipped or probably more commonly the release thrust bearing has failed. Probably can see the difference between the two sides if you can get someone to pull the levers while you watch.

I believe it is also possible for the bearings on one side of the bevel gear in the middle of the rear end to collapse and allow the whole cross shaft to move toward one side. This would have the effect of reducing free travel on one side and increasing it on the other. However, I expect you would probably see that the free travel returns to normal when the clutches are pulled with the main clutch disengaged.

I was down your way last weekend for a family get together!

I'm not the one to ask about repairs to a a D4 of any stripe. I don't own one, never even touched one, much less worked on one!

I would really look closely at the linkage and adjusters, comparing the two sides. I would hate to see you tear into it when you might be able to reach in and replace some pin or nut etc.

That being said, I think you do remove the cover and the bevel gear shaft comes out whole with the clutches somehow. I have seen a picture of that assembly being removed. in comparison, much better than the D2 where the track and final drive have to come off each side, but not as good as the D6 where the individual clutches can be unbolted and lifted out the top.
