Reflux can damage one kidney more than the other. If one kidney is badly scarred it might need removing for two possible reasons. Firstly a damaged kidney can cause high blood pressure. This will need life long treatment with drugs to prevent the blood pressure damaging his blood vessels and other organs (including his good kidney).
The average cost for a rear main seal replacement is between $659 to $860. Labor costs are estimated between $631 to $797 while parts are priced between $28 to $63.
How much would it cost to replace the rear main seal? I know a lot of stuff has to be removed to reach it, but the damn part is only $20 and I have a hard time thinking I'd really be paying $820 in labor. Also, I need to know if 162k miles sounds normal for such a repair.
