So far this year I've spent about $4200 on my truck: lift pump, injection pump, power steering pump, front & rear brakes (with rotors) and have 120,000 miles on my 2001. What's likely to be next that'll cost a bundle? When do you stop repairing and replace the truck? I've never kept any vehicle this long and for this many miles so I don't know when the swap point is. I know the engine can go on forever but when does it become not cost effective to stop fixing? Advice? Thanks.
