did you guys install your gears your self or did you have a shop do it?

 

If you have a dail indicator or some other way to measure runout and gear lash you could do it yourself.If you don't have the tools to do it right,take it to a reputable shop that does have these tools and will stand behind their work.You can't just "eyeball" things like this!If not done correctly there will be unpleasant noises and short gear life.
