Help, I have had to replace my power steering pump three times in the last six months on my 2015 Kenworth t680 . three different shops so it is not mechanic error. is there anything else i should be looking at.
Is the pump still mounted in the original position from the factory?
I had a problem with my power steering fluid getting too hot because the pump was mounted too close to the radiator from the factory. Kenworth came out with new mounting brackets that moved the pump further back away from the radiator. Solved my hot fluid problem.
It may be your issue too.
