my buddies and I have put 4b's into our wheeling trucks. he recently had a power steering pump failure, mostly with the front gear and adapter. his a direct drive pump. it came out of a chevy chasis bread van. can anybody tell me where to get the thing rebuilt. It broke the shaft inside of it and cummins wants a fortune for parts. will buy any spare parts you may have. It doesn;t have any other accessories just the power steering pump. thanks
