As the clearance between the 2 parts increases, the bearing surface (and therefore support) area decreases, the spot contact pressure increases. That causes the bearing to run hotter (here the oil may burn) and as well, it will wear faster.

 

While not super critical in this particular application, it also causes the shaft to run off line that it was designed to run on. With some installations (not really so here), that can cause wear on other parts, mesh of gears not to be correct and on it goes.

Hi all, another question, if I get the diff bushes out to 0.001" will I have to redo the diff side bushes too ? The driveshaft ones.

Check them - if they are OK, let them go, if they need doing, do them.

Those in the diff itself that we have been discussing don't do a lot of work, they only come in to play when there's a difference in speed between the 2 front wheels, however those in the side covers are working whenever the car is moving.

What should be the clearance on these bushes ? the same ? 0.001"
