Gear

Is there a left and a right leg or both the same.

Any tips on installation?

I think they're the same. I hope!
Make sure you use the reamer Vans recommends. 0.311" I think.
I buffed off the burrs inside the towers and the gear then applied a light lube before sliding them in. They fit pretty snug.
 
If memory serves me right, there is a left and right but it was about 8 years ago when I installed them and my memory is not as reliable as it used to be.
 
Thanks ,I will yank them out and see how they look switched around. At present they kinda look ok . The sweep must be very minor.
