Hi dwp,
Have you tried the 'Team Tech Tip' Build guide here?

There is certainly no design issue with the ball diff being able to have enough pressure exterted on the thrust balls. I can tighten my diff up so that it is a spool if need be, it's not a great thing to do as it will flat spot you plates and balls but I can assure you on a correctly built diff you can do this.

What grease are you using on your plates and balls? Incorrect use of the wrong type of grease can make your diff operate incorrectly, but I doubt this will be the full extent of your problem.

Another explaination for your problem might be that you have an out of tolerance part in your diff. We can't check this with you contacting the support staff at TD directly.

Please contact [email protected] and someone will get back to you directly.
