Best reason EVER!!!!

Alternator is likely going to fail soon.

Hell of a good job tracking that problem down, buddy! Kudos, sir!

Nuff said... Run it till it dies and junk it

You could definitely get a few hundred out of the 4.8 if there's nothing wrong with it. Record a video of it before you pull it.I like the idea of throwing a few mods at it while it's pulled, that and a tune will be quite noticable!

Certainly not worth the money/time/effort unless you've got to replace it for another reason in the first place.

Hell, that's worth a swap in my opinion!lol For the record, depending on the year/version it's about 40 lb-ft

I had a 4.8 that was leaking coolant into the oil... I was short on cash at the time and couldn't upgrade the trans too so I swapped in a junkyard 5.3. Used the intake and everything that came on the 5.3... Didn't even change the tune. Fired up on the first try and has been running for 3 years. Power difference is SLIGHTLY noticeable, would likely be better with a tune... But now I have the 6.0L itch... So...

Hey... If it works, it works!

I replaced my lid a few months ago with the same replacement. I've not seen the foam sold separately but it shouldn't be too bad to replace with any type of upholstry foam like Chris said... I would gladly send you mine.... but uh... I got pissed and threw it out the window one night.... long story.

I would have given them $1000 for it just for the parts!

... And the dealer they took it in to trade offered them $1000 for it and they took it! Wow... http://www.truckinweb.com/webonly/1501_like_a_rock_2003_chevrolet_silverado_still_going_at_790000_miles/

Got her cleaned up today, gotta LOVE this southern weather! I think the 2" rear drop is just about right! Sorry for the crummy cell phone pic...

This thread gave me the motivation (as well as the 60+ degree temps outside today) to get off my arse and put my rear drop shackles in. I used McGaughys 2" drop shackles (33037) that I bought back in November... I've been having a random no start / no crank condition that was getting worse on cold mornings, so I got that sorted out (it turned out to be the starter). I also changed the oil, So I'm enjoying a much deserved beer! The sun went down before I got the chance to wash it, but the high tomorrow is supposed to be 61, so I'll get it then.

Muchas Gracias! It has very literally been babied! I'm ready for 306,000 more!!!

Mine too! I rolled over 306,000 miles on the way into the office this AM. I replaced the original 4.8L motor with a junkyard 5.3L at the 220K mark, but the trans and rear are untouched and original. Other than that, just routine maintenance and wear items replaced... I just chronicled my maintenance history and my upgrade list for this year in another thread http://www.gm-trucks.com/forums/topic/148370-gmt800-talk-chime-in/?p=1553630 so I wont repeat it here. But I'll gladly post the picture I took of it after I washed it the other day.

Same here! I've been a member here for a while but I normally just lurk and learn! Your post prompted me to share my GMT800 journey. I have a 2003 Extended Cab Short bed that I bought in 2004 with 24K miles on the clock. It now has 306K and climbing! It has been my daily driver, day in and day out for 10 years. It has made all of the vacation trips as our kids were growing up and it did everything I ever asked it to do without failing me, every time! I love that dang truck! Alas, as you can imagine... She's getting a little long in the tooth. I've done 100% of the maintenance myself in my own garage with common tools. I'll recap her long and storied history here: First off, The biggest issue I ever had was some coolant that was leaking into the oil at about the 220K mile mark. It was originally a 4.8L, so rather than dealing with a potential castech head issue, or blown head gasket or trying to track down and repair the problem on an already high mileage engine, I bought a 5.3L from the local salvage yard. Out with the old and in with the new (to me!). Yes, I guess you could view this as a failure or weakness in the GMT800 platform... But I'm a glass half full kind of dude. There are so dang many of theses things out there that they are easy to find and they are VERY affordable. AND they are all the same, so the swap was a piece of cake. If this one ever falters, I'll do the exact same thing again! Other than that, its all been what I would expect to be regular "wear" items after 300K + miles of use... Over the years I've replaced the following: Fuel pump, water pump, brakes, rotors, shocks, alternator, power steering pump, front hubs/bearings, A/C compressor, knock sensors, cam position sensor, spark plugs/wires, battery, tires, fluids and filters... She starts and runs and goes every time! With that being said, I've had the itch to get an old truck to hot rod up a bit... I've also had the itch to get one of them shiny new fangled trucks... I also refuse to go into debt to have either of those... So there in lies the dilemma... I've made the resolution this year to satisfy those two itches with my ole GMT800. The way I see it, I can make a truck payment to myself and then buy the parts when the money is there. So my 2015 GMT800 wish list is as follows. Have the rear end re-geared. Right now, it is an untouched open 3.42:1. I have a good local shop that will do the work on this one, its definitely out of my league. I have chosen a 4 clutch posi type unit and 4.11:1 ring and pinion. Will also replace axle bearings and seals at the same time. Probably replace u-joints as well. Have the 4L60E rebuilt. Same shop will do this work. Again, aside for fluid and filter changes, this is the original transmission. I'll likely be going with a Monster transmissions "Mega Monster in a box" rebuild kit. Valve train upgrade Comp Cams K54-424-11 kit that includes cam, lifters, valve springs, retainers, lock and seals. Add new pushrods and some adjustable rocker arms. Will also likely replace the timing chain and oil pump at this time. I'll also get a list of mods to BlackBear and have them do a custom tune. I would also LOVE to convert it to the larger radiator and e-fans. Appearance upgrade Some of the clear coat is starting to peal on the roof. So a repaint will be the last on the list. Still kicking around paint schemes and ideas. Probably wont decide what to do until the day before it gets painted. I already have the shackles to drop the rear 2". Just need to put them on. And of course new wheels and tires. Nothing outlandish... but something a little cooler than the 16" steelies that are on it. Long story, short... I think it will make for an even more awesome-er truck. It will have all the get up and go I want and will (eventually) look good doing it. I'd love to hear any input that y'all may have! Attached is a picture as she sits right now!
