I'm looking to keep my 2001 LT 1500 Suburban 4wd another 2 years. It's been a great vehicle- we've spent many vacations traveling Colorado, NM, and Texas in it. It's been across Engineer Pass in Colorado at 12,000 feet- no small task. I hope to use this forum to get some tips on maintenance to keep it in top shape. It has 84,000 miles. I'd like to replace all brake parts and upgrade/replace shocks. Also looking for tips on tune-up and other engine maintenance items.
