Back in 2003, I worked as a manager which sent our customers vehicles to k&b. Over a two year period equalling thousands of dollars worth of repairs..Brett the employee at the time, was seemingly courteous and qualified. So with the history I had with K&b, I sent him my own transfercase to be rebuilt. I told him whatever it takes to repair no problem. I paid 138.00 which included a couple of seals and an internal inspection. I installed the unit in my plow truck, and on the third run down my driveway it began to grind away chain slipping over gears just like it had before! I called brett up and explained what happened. He agreed to try again with another unit. I told hin I would pay for any additional parts but no additional labor. He agreed...Two years later..I repeatedly had called with no response! Finnally he had returned my call and said he now owned the business and was not going to fix the second delivered case. At this time the case is still in his posession, I still have a truck which grinds continually and I'm out 138.00 and two 40 mile roundtrips to ellsworth maine . You can draw your own conclusion...
