driveline yoke slop/ traction bar fix?

[jadegreenimron]

When I take off I get a snap from the yoke moving in the tranny. I know this is the cause because if I grease the yoke it will be fine for a few weeks.

I was told that if I put on traction bars this will help to eliminate the rear end from flexing and will hold the yoke in place better.

Opinions?

Thanks!
