Purchased a Rack and pinion and power steering pump for my vehicle. They didn't tell me I needed a pressure line as well so I had to buy it locally while my car was on the lift. Also installed a P/S filter. Rack leaked from day 1. 3 leaks. Wouldn't refund because it was more than 30 days from purchase. Would only warranty replacement part which I have to buy up front and wait for my refund after I return the piece of crap they sold me. Need another new pressure line and because fluid leaked out the new pump needs to be replaced too. They won't do anything about the labor to do the job again. Their crap part is going to cost me another $800 to fix again and I have no assurances from them that the next one won't leak either. Will NEVER NEVER NEVER buy from them again.
