Hi Ed.

Did you have your chassis guy put a brace on the housing when you took it to him last time? There is probably a bad tooth on either the pinion or ring gear. Pull the cover and look for cracks. The gears wont last very long if the clutch is set with too much pressure. The 617 has a very small pinion and not very durable. When I ran a stick in my car many years ago I was only able to get 50 runs max from my Dana w/ 617 gear but that was before the good clutches and clutchless gearboxes that are available today. Good luck getting the car back out and running. I hope your back gets better so you can get back to driving soon.
