So I've had my 1998 c1500 since... well... 1998 when I started driving. It's been my one and only vehicle for these past 13 years and I love it! However, at this point, it's beginning to really show its age. I understand general maintenance and do my best to keep it running. My question to you all is, is there a good list of parts (hoses, sensors, etc...) that need to be changed out at varying year markers? I have yet to browse this entire forum as I just joined, but I plan to do so. The reason I ask is I've recently come across issues such as coolant leaks, brake slippage, rich exhaust smell, excessive play in the steering wheel, pulling to the left and right, etc... and I'm not ready to spend a ton of $$ simply troubleshooting every possibility. I'd like to update the system with new components if they've passed their prime and THEN troubleshoot any continuing issues. Obviously I don't know a whole lot in this field which is why I bring this to you. Any help is appreciated!
