thanks I am a " mechanic " but its raining here and you saved me from rolling around in the mud to figure out what was going on thank you for taking the time to make this video
I'll have to keep an eye out for it; it'll definitely save a lot of hassle. I know Amsoil makes it like that but didn't know Valvoline did. I'm surprised I haven't run across it yet.
The front differential on the 99-06 Chevies is more important than you think. I have a 2000 Silverado with an autotrak 2 where the buttons are on the dash. This 4wd design is crap and they changed it in the 07 and forward. Unlike older front locker trucks, the front driveshaft always spins and the cv axle splines are directly connected to the front wheel bearing hubs. The connect/disconnect is physically in the transfer case which wears out the front diff and parts around it.
That's a good point. I've seen evidence of my front diff seals leaking and attribute it to the unnecessary movement of parts that are not in use. All in all, I'd say having them last 290,000 miles suggests it isn't all that bad of a design, but it would be a whole lot better if I didn't have to replace them soon.
@@funcle_kevinMy 2000 Silverado 1500 has 315,000 but I only got it at 246,000 so I don't know the history. The 5.3 is great but has always had rattling valves because of a factory issue, it sounds like the timing is off at 40-50 mph half throttle. My machinist has the same truck with 360 thousand miles and his does the exact same thing. He said putting in new valve guides on customer vehicles has fixed the problem before. It leaks a quart every 1,000 miles. The transmission has never leaked on me and both differentials seem to be original. If you ever change the transfer case fluid on these trucks know that the lovely engineer that designed them decided to make the housing out of magnesium (extremely flammable) and the fill and drain plugs are aluminum. They will not come out. You have to use a heat coil gun over the bolt head or a really good heat gun. I have never seen the 18 mm aluminum bolt heads not strip out, which mine did of course. Apparently it is such a common problem there is a GM Service bulletin on it.
@@buttonysquare8501 I've been fortunate in that I haven't had those issues. I know there was something questionable about the heads they used early on, but can't remember which castings were the good ones (799 rings a bell). My engine is the L33, which is all aluminum. That might be the difference. Also, I wonder if in addition to worn valve guides (or a broken lifter), you might be hearing the sound of a loose timing chain. I changed mine around 200k and it was a bit loose when I took it off. There was some rattling before then, but I wouldn't relate it to timing, at least as far as performance goes. A trick to avoid the stuck plugs on the transfer case is to change the fluid every 30k miles so it doesn't seize up. I'm guessing the previous owner ignored that part of the owner's manual. My friend has a 2010 and his front diff fill plug basically needs to be cut off each time he changes his fluid, but that has a lot to do with his own neglect of maintenance. Good luck with it all. Luckily, it's a very easy platform to work on and the parts are relatively inexpensive.
@@funcle_kevinIt's been doing the rattling/pinging noise for the last 75 thousand miles I've had it. It only does it at about half throttle between 40-50 mph. It sounds exactly like detonation would sound from a motor that isn't timed right. There are no timing related sounds and it idles great. It sounds great at every other speed. I've always had piston slap that these motors have on a cold day where the piston skirt coating wears off and there is too much clearance until they warm up. People will complain that they "diesel" when cold, which is this noise. My machinist has the exact same truck (2000 Silverado 1500 with the 5.3 and 360k) and was surprised when I asked him about it and we had the same issue. From what I've read online not many people complain of it, but the ones that have mentioned the same issue say it is a valve guide clearance defect from the factory on the 99-02 models. I did not tell that info to my machinist and he told me that other people have brought him the same motor with the same complaint before, thinking the motor was about to blow up. He said he would do full head jobs and the motors would still do it until a different time he changed the valve guides too and that fixed the problem. I've been driving it for 5 years straight everyday for work without issue. I came in several months later to get some drums and rotors turned for a 79 F250. The same machinist was actually talking to a guy when I was there that happened to also have a another 99-06 with 569,000 miles, supposedly all original major parts. The previous owner actually sold the truck thinking it needed a motor but I've just been driving it. According to the earlier forums I was reading on people were saying some live forever with the issue, others with the problem already dropped a valve and are in a junkyard. Thanks. I subscribed to help you out.
What about playing Carly Simon’s "Anticipation" song while the oil is draining out. The song is not just for selling Heinz Ketchup or waiting for Cat Stevens to pick you up for a date.

I'm glad the video helped you out! Nothing less fun than working on a vehicle in bad weather (which reminds me, I'll likely snap an axle soon).
Good stuff man! Thanks for the in depth detail
I'm glad you found it helpful, and I appreciate you taking the time to let me know.
Hey brother heads up.. Valvoline makes gear oil in a soft plastic bag that fits almost anywhere.
I'll have to keep an eye out for it; it'll definitely save a lot of hassle. I know Amsoil makes it like that but didn't know Valvoline did. I'm surprised I haven't run across it yet.
@@funcle_kevin I got mine at good old wally mart.
@@davidmiller2257Yes, the “discount city” use to sell it in a plastic bag. Bought some to replace the oil in the gear box on my mower deck.

Great commentary Tom petty 😂

you want a bad joke ok here it is. why did the chicken cross the road? because there were no cars coming.
Nice!
