Tech Question

Shannon Fuller, Salisbury, Australia, 1970 Dodge Challenger 440

I’m a long time reader of MA and always enjoyed your tech articles. I havefinally got a problem that hopefully you can help me with. On my ’70 DodgeChallenger, I’ve had the Green Bearing kit installed by a local diffspecialist, however, when I’m installing the drivers side (Left hand side)axle, it binds up as I’m about to finish tightening the retaining nuts andwill not turn over. Any idea what the problem is here? Is the bearinginstalled in the wrong position or have I forgotten to put some kind ofspacer in?

Thanks very much for your help!

Shannon, I see only three possibilities: Either one (or both) of thebearings wasn’t pressed on all the way; or one (or both) of them aredefective; or the thrust spacer (on clutch-type Sure Grip) has fallen out onone side and the axle is attempting to mangle it.

Of course, there’s always the possibility of mismatched parts, but you ddn’tmention swapping anything. In other words, if you’re using axles which aretoo long for the housing (from a different body style, aftermarket ones cuttoo long, etc.)

By the way, you DO know that those Green ball bearings have MUCH lesscapacity than the stock Timken tapered roller bearings, and are recommendedfor straight-line (read: drag racing) use only?
