Replacing Ujoint - rubbing?

[pklarkin]

Hi all,

I'm in the process of replacing my old ujoint with a new one. New ujoint with original inner cap and outer housing. The new ujoint is rubbing against the inner cap. I've checked to ensure the joint is seated all the way in on the end of the main drive shaft. Checked the fit with the gasket in place - same issue. Any thoughts? Could the replacement part be defective?

I've attached a couple of pics for reference. New joint is on the right side of the first picture, and the left side of the second one.

Thanks for your help.
