If you end up with prop vibrations to cure it you'll need a new prop. Either DC one or wide angle.

To follow on from Steve's handy post, independent of how you choose to manipulate your caster angles, lifting a vehicle will cause accelerated wear on the prop UJs. I can't remember the exact numbers (long time ago) but for every additional 5 degrees of angle, the wear rate on a UJ increases by somethig like an order of magnitude. A DC prop will halve the working angle on the UJs at the transfer box end, meaning they'll last longer. A wide yolk prop has a wider working envelope (it can work at a greater angle without binding), but won't last much longer than a standard prop as the working angles don't change (same rate of wear).

My preference would be to go for a DC prop first, unless your building in a lot more flex into the suspension. In which case, a wide yoke, DC prop would be just the ticket (and they are readily available courtesy of Saginaw for reasonable money) - best o' both worlds.  :wink:

If you do want to change the prop, try to steer clear of the big retailers and go to either a specialist prop maker or scour the 2nd hand market - you'll save a small fortune.  :wink:
