#328 of 2018 rear end problems on two different s-10's
Aug 21, 2003 (5:08 pm)
I owned a 98 s-10 2.2 liter 5 speed, rear seal was leaking at 7,000 miles. I had it fixed at dealership no more problems. Then they had a recall on my plug wires, truck ran like it had bad gas in it. fixed it with no problems. I was towing a lawn equipment trailer with it so i figured it was under to much stress, so i traded up to a 2001 4.3 liter extended cab, no problems till 40,000 miles when rear end on it started whining. Took it to dealer, they said rear end was bad and would fix it under good faith. A week later driving interstate rear end sounded like it was going to fly apart. Out of oil in rear end again, so i took it back and left it for a week. They put a new hub on rear end plus changed out all of the drive shafts, now it has a vibration in it. They say that it's because i lowered the truck two inches, and that there is nothing else they can do with it. So now i have it at another rear end specialist to see if i can it fixed for real this time, AS SOON AS IT IS FIXED I AM TRADING IT IN FOR A TOYOTA AND AM NEVER OWNING ANOTHER CHEVROLET. I BABY MY TRUCK I DONT HOT DOG OR SPIN THE TIRES, SO I DONT UNDERSTAND WHY THIS HAS HAPPENED TO MY TRUCK TWICE. DOES CHEVROLET HAVE PROBLEMS WITH THEIR REAR ENDS? ANYONE ELSE WITH SAME PROBLEMS?

Back in '93 when I bought my Nissan Sentra, I was at the dealership (GMC-Nissan-Pontiac) and saw six of the eight lifts being occupied by either S-10 pickups of Blazers. There were approximately 20 new complete rear axle assemblies stacked on the service department floor.
I asked the service manager what that was all about and he said that the S-10 series suffered from "a lot" of rear differential failures.
Now, I have known people with better than 100,000 miles on their S-10 series trucks that have never had a problem. My son, who was the unfortunate owner of two S-10 PUs, never had a problem with the rear differential, either. Plenty of other problems, but not that.
I have known two individuals that have had a S-10 rear differential pop. I don't remember the miles on them since this was a while ago, but both were out of warranty.
I think you will find that rear axle failures are more than likely the result of incorrect machining or assembly from day-one that will affect a certain percentage of units manufacturered. Ford, Dodge, and Toyota have had problems in this area, too. In fact, Dodge use to buy rear axle assemblies from GM for the full size RAM (American Axle) some years ago and they had about a 4-6% failure rate, which is just about the same for GM full-size trucks.
Toyota Tundras are not exempt, I might add. About four months ago I saw one changed out at my Toyota dealership.
#330 of 2018 fuel pump problem

I think my fuel pump has gone bad...i've been hearing that this isn't too uncommon with this truck. Is what i'm hearing true?

In responce to the wiper motor fix that was posted here recently, Wanted to add that this does work. I have an S10 Blazer that had that problem. Did just as the person described. But one thing to add. You will also want to look down the side to find a burned out circuit. I had it and used a stripped piece of telephone cord to fix the circuit. But since then I've had no wiper problems. Took all of 5 minutes to do.

cage47, don't know if you know that GM recalled the wiper motors, supposedly replacing the circuit board. I have a 97 Sonoma and got the dealer to replace the board for no charge. So far, no problems yet.

But it only includes models up to the 1997 year. I have a 1998. No luck. Why sweat it when the fix is so easy? What I'd like to see is the ball joints recalled to be replaced with grease fitting units. Or the Oil coolant lines.
#334 of 2018 Repack front wheel bearings
Oct 07, 2003 (7:40 am)
The service schedule on the S10/Sonoma shows that front wheel bearings should be repacked every 30,000 miles. Is this for both 2wd and 4wd, and does anyone actually do this?

Repacking front wheel bearings on 2wd is required every 30K, i did mine last year.Not sure on 4wd they may be sealed.
Oct 20, 2003 (7:54 am)
...You are correct. The front wheel bearings on a 4WD are sealed units.

What date was your 2002 built? Check the door jamb for the month and year. Does the noise occur only on startup and then go away or all the time in traffic? Finally how hot is it when this occurs?
