Hello, where would be the best place to go to buy a ring and pinion?
I can hear my gears clanking together in the rear when I speed up or slow down, I think that's what is causing the problem, but I could be wrong. What do you think?

 

Check U-joints first. Verify where the slop is. No point in changing gears that are fine, only to have the T-case blow up on you.
