[Vwdiesel] Front intermediate shaft bearing

1/4in? Wow! How do you develope any oil pressure?

You could be a victim of over-honing in part of the rebuilder. There are
two types of replacement bearings... actual size, and hone to size.

Is the play in only one axis or all around? A way too tight belt may
cause premature wearing of this bearing in one direction, but usually
the injection pump suffers the same fate.

Perhaps the shaft was machined, albeit, improperly.

If you can, get in there and mic the shaft journals and bearing inner
diameters. All four should be the same relatively. See which of the four
measurements are way out. If the bearing is way out... over-honed. Front
journal way under, over-machined or wore.

Based on you description of the bearing, you have the shaft already
removed. Go ahead and measure the journals.

This should tell you which direction to go.

Troubleshooting by wire since 1994.
