2008 Chevrolet Silverado 1500 LT2 4dr Extended Cab 5.8 ft. SB (5.3L 8cyl 4A)
I bought new a 2008 LT with Z71 package. It now has 116,000 miles on it. I would like to say trouble free, but that has not been the case. I change the oil myself every 10,000 miles and use Royal Purple and a top of the line filter. I have never had to add oil between changes, so that part is all good. Now for the bad. (A) the fuel line ruptured spraying gas all over, including in proximity of the catalytic converter, forunately now fire resulted. Even though it was off of warrenty the dealer fixed it for free as it was a safety issue. (2) at around 90,000 miles I noticed that the cover on the left CV joint was torn, and grease was everywhere. I had to have that repaired and in the process a new wheel bearing was installed. (B) at 116,000 miles the right wheel bearing failed. I have never had a wheel bearing failure in any of the vehicles I have owned, and I dont understand this. I don't work the truck hard, it is not used in harsh environments. Other than these issues I like the truck, in fact, there is nothing I don't like about it, but this causing me to consider another make other than GM for my next truck.
2008 Chevrolet Silverado 1500 LT1 2dr Regular Cab 4WD 8 ft. LB (4.8L 8cyl 4A)
Had to list this as a LT regular cab long bed, 4 wd. Actually is an LS, which in 2008, was just a Work Truck with a chromed front bumper and chromed steel wheels. Mine also has "Trailering equipment package", which is the same as "Towing package" without the locking G80 rear differential.
It has the 4.8 with 4 speed auto. No power windows, no power locks, no cruise control, no power mirrors. Has A/C. The 4.8, thankfully, did not have the variable cylinder engine until a few years later. Then the 4.8 was dropped entirely.
I purchased it new in Sept., 2008 at the old GM's fire sales. Truck was made the last week of 2008 production in June 2008. At their best plant at the time, Ft. Wayne. It has very dependable with almost no problems I do all maintenance on it. No rattles or squeaks at 65k.
Currently at 65k miles. It has seen all sort of use from heavy urban gridlock to local country roads to Freeway use. I changed out all fluids between 50k and 60k miles. Brake, coolant, transmission, front differential, rear differential, and transfer case fluids. This year, at 62k miles, I replaced the front and rear brake rotors , drums, pads and shoes. The rear drum shoes were almost done, but the front pads could have gone another 10k. Engine consumes almost no oil between 4k to 5k oil changes.
Non wear items replaced since new:
--Rear shocks were shot at about 40k. Replaced with KYB gas-adjust mono tubes which are great and match the front strut valving well.
--Turn signal clicker not audible at 50k. Sound for TS comes from left speaker. Unbelievably cheap paper door speakers replaced with cheap Pioneer speakers. --All good. ( common problem).
I attribute the good reliability my Silverado has had to the fact it doesn't have the things that frequently cause trouble on the GMT's.
--No cylinder deactivation on the 4.8 in that era. No piston ring/oil consumption or camshaft problems because of that.
--No power locks or power windows which cause many problems.
--No Eaton G80 locker rear differential which some people have experienced failure with. With manual shifted 4wd and an open rear axle I have had no trouble --making it through even heavy snow.
Due to the lack of any power accessories and being a regular cab, the truck is fairly light. I believe this 4.8 can easily match or beat the ubiquitous 5.3 with extended or crew cab 1500 in acceleration.
It has a very wide turning circle, but the use of rack and pinion steering starting in 2007.5 makes it pleasurable truck to drive.
Gas mileage is not so good. When I commuted to work, with a total mix of driving, I averaged about 15.5 mpg. Mostly local roads and shorter trips now. I seldom see more than 14 mpg. It will still do 17 to 18 mpg on infrequent Interstate highway runs. No mileage bonus with the 4.8 over the 5.3.
Used buyers may like to know that GM in 2008 and post bankruptcy, 2009 made up different equipment packages that did not exist in catalogs. You may get something that shouldn't have been on your truck ( sometimes heated power mirrors on an LS trim) or not get something that should have been included.
2008 Chevrolet Silverado 1500 LS 4dr Extended Cab 4WD 6.5 ft. SB (4.8L 8cyl 4A)
In my experience this is a good, but maybe not great truck. Kind of a hybrid between a station wagon and a truck, lots of room and comfort in the cabin, not a lot of bed space. I've had a few irritating problems, like having to replace one of the seat belt latches and tire pressure warning lights that don't work, but nothing major. I'm looking for a new truck to replace it and will end up choosing either a Ford F-150 or another Silverado, probably the extended cab though rather than the crew cab model. I'll just go with the best deal I can find.

2008 Chevrolet Silverado 1500 LT1 2dr Regular Cab 8 ft. LB (4.8L 8cyl 4A)
I have over 5 years and have 45000 miles on it. It has had excellent reliability. I'm still on the original tires. I will replace them around 50000 as they will need it. The only thing I have needed to do was change the front brakes on the truck around 18000 miles and I had to take the truck to the dealer around the 2.8 year mark when the pass door lock stopped working. Apparently this is common because there was another (2007-2012 Chevy Silverado 1500) owner in front of me getting the same pass door lock replaced. Also I had to add some coolant around the 1.5 year mark because in traffic it would start getting warmer as in not in the middle of the gauge where the temp is supposed to be.
Drives great and has been reliable so far.
Make the door locks stronger. Occasionally it idles rough, starting around 800 miles, so far no issues but its made me wonder. I got a notice letter from Chevy but the dealer (Hudiberg, OKC)told me if they inspect it and find nothing wrong I would owe them the hourly maintenance fee.
