Just recently bought a 2001 Grand Cherokee with 168,000 miles 4.0 engine. I am using it to haul my tractor around and was looking for suggestions of what to do to it. So far I have replaced all 4 shocks, The hood shocks, the lift gate shocks and will be putting in a high volume oil pump later this week. Overall the jeep is in good shape and runs really good. Suggestions I am looking for is things to help with towing the trailer. Thanks.
