High Mileage Suburbans

    i have a 1999 suburban 1500, that had a 5.7 vortec that is now gone, i was wondering if a 1997 350 v8 suburban engine would work, or do i have to stick with 5.7 only from only a 1999, or is a 5.7 vortec, the same as a 350 v8?
  • I have 99 that I bought brand new in 2000, I just turned 485K on it, still working great

    good luck
  • Wow! My mechanic says that the 92-99 represents the longest-lasting Suburban body style ever produced. Industrial strenght 350 cast-iron engine and built really well from tip to toe. So, you may make a million!

    My 2003 just passed 98k and I am seeing lots of signs of aging, nothing that will ground it - just little things (well one big thing - the front differential is spitting up metal shavings and we are changing the gear oil every 2k to see if it stabilizes - if not, that's about $2k).
  • 2001 LT 4x4 99K - has a high idle and shifts late and hard when hot. Suggestions would be most appreciated.

    Wife wanted a knew suburban, so we went shopping the other day. There are some decent deals out there for low mileage used suburbans, but would still mean payments for us. Prefer to fix the one we have and drive it as long as possible.

    I've enjoyed reading this thread and hope that it picks up as well.

    I have a 95 suburban 260,000 + miles and other then normal maintence and few typical issues of things just waring out this dang thing wont die. lol. yes original 350 engine. purrs like a kitten. I love this thing!!
  • I bought my '03 Suburban new, just turned 205k with no issues other than maintenance stuff. I've been shopping for something with lower mileage, but I think I've just decided that I'm keeping it for the duration. I just can't justify the money when it's been such a great truck, and shows to signs of slowing down.

    I last posted this here in 2008: "My 2002 1/2 ton 4x4 Suburban LT now has 159,000 on it and we bought it new Dec '01."

    Now our Suburban, named "Hammerwhang" has 260,000 on it and it's still running perfectly and continues to be our lowest maintenance vehicle out of 40 that we've owned and also the most reliable.

    Since my 2008 post, I've continued to change the oil about every 13,000 miles, optimizing the runtime of the Mobil 1 EP synthetic oil by having Blackstone perform their excellent spectroanalysis after each oil run and it continues to run very clean. This service has been key to saving money on filters & oil (even though synthetic oil is expensive) and it's also given peace of mind about the internal status of the 5.3 engine.

    Routine maintenance aside (which I mostly do myself in my home shop), in the last 6 years I've replaced the control arm & idler arm, the alternator and one window lift motor ($50 new on eBay, took 45 minutes). That's it. However, this month I'm going to replace all the moving parts in the front end for its first-ever rebuild: Hubs with ABS sensors, CV shafts, axle seals, tie rod ends, all 4 ball joints, and bump stops. I'm having this work done rather than do it myself because it's just a little outside of my expertise and I have a guy who's done hundreds of these and runs his own small shop @$50/hr. I will also replace the 4 shocks on the Autoride suspension for the 2nd time. This will all cost about $3,000 but when you consider that the entirety of repair bills only come up to $4k in the last 6 years/101k that's only 4 cents/mile which is cheaper than any other car we've owned. In fact, even if I include regular maintenance items it only totes up to 6 cents/mile.

    As always, we keep the truck inside, drive it ~15k/year nowadays, mixed city & highway. Several times per year we fill the cargo area up in a way that no other regular vehicle can match and we occasionally tow our 5,000 # travel trailer. The Sub's been around all 4 corners of this great country several times, it's moved our kids and businesses, handled countless errands short and long, taken my wife & I on memorable trips in fabulous comfort and has never let us down save for the minorly inconvenient alternator failure at 255k miles.

    I hate that GM wrecked the cargo area design on the '07 series Suburban, which in my opinion removed much of the "U" from this amazing icon of an SUV, and the '15's are no better and perhaps worse (yes I've driven one and loved everything else about it but I refuse to spend $75k on an ill-designed-cargo-space S_V).

    We fully intend to drive our '02 Sub to the end of it's useful life, or ours, whichever comes first. I will fix whatever it needs and run it forever and then will it to our kids because it's the last of the Great American SUV's. They just don't make them this way anymore. If I lost it somehow, I'd look for the best same-series '06 and buy it immediately.

    Love my '06 Black Suburban. Mileage is currently at 157,000 and that 5.3L still purrs like a kitten.

    The fuel pump problem is most likely from running low on fuel too much.The fuel is used to cool the fuel pump.
    Yeah i know,I don't remember this problem years back. I guess fuel injection needs a better pump. I would consider going crazy on filters. Aftermarket fuel and transmission filters could save big money. A bypass filter for the engine and a filter for the power steering also. Leave the stock air filter box on and the paper filter. Change the brake fluid and go over wires and connectors.Think about how much a new vehicle costs. Add in that Suburbans really haven't changed much over the years. I write this after much research and the thinking about what year Sub. to buy. I think of them as a big four wheel drive station wagon for the family,That can tow good.
