#10 of 35 Chevy s10 Bad vibration by david23we45 Feb 07, 2008 (4:07 pm)
I own a 2000 s10 extreme it has a bad vibration in all speeds i checked the U joints and they seem tight to me and it has a fresh tranny rebuild i raised the rear of the truck to check the rear end on the passenger side of the truck i can grab the tire and it moves in and out anywhere from an eighth to a quarter inch the drivers side is tight Does this mean the axle bearing on the inside needs replaced and could this be the cause of the vibration?

Replying to: david23we45 (Feb 07, 2008 4:07 pm) I'd say it's a good bet. Usually along with the symptoms you mentioned you would hear a roaring sound, unless the noise is drowned out with mud tires.

Replying to: bstep1971 (Sep 02, 2007 7:29 pm) Iam having the same proplem with my '96 S-10 and a friend told me it is the carrier bearing(the part where the 2 shafts come together right under the floor boards and seats.It is very annoying and a little scary sometimes,good luck..
#13 of 35 Rear end vibration in Sonoma by 2dusty Apr 03, 2008 (3:21 pm)
I just bought a 2003 GMC Sonoma and it had a constant vibration when I tested it. The dealer replaced the u-joints and hanger bearing and had the shaft extension put in and balanced. That seems to have reduced the vibration considerably however, I still have a vibration when accelerating from a stop and it is slightly detectable at under 100 KPH. That's about 50 MPH. The rear end was lubed as well. Any suggestions?">
#14 of 35 Fuel pump problems by ohiaboy May 29, 2008 (11:14 pm)
I have a 93 GMC Sonoma 2.8ltr, and i have no power from the grey wire to my fuel pump. i have tested the wire from the fuel pump relay, and i have power. i have been told that it is the oil pressure switch. i was also wondering if anyone knows where i can find the fuse box diagram online. If anyone has any info please email me at richardKoonhotmail.com Replies to this message: gonogo (May 30, 2008 8:22 am) ohiaboy (May 30, 2008 12:05 pm) gonogo (May 31, 2008 7:04 am)

Replying to: ohiaboy (May 29, 2008 11:14 pm) The gray wire from the relay goes to the fuel pump. On the way to the pump the gray wire connects with the pressure switch wire.  I would suspect where they connect, most logical is at the switch. If the pressure switch has one wire on one side and 2 wires on the other, the 2 is the connection. If not, good luck looking.  The pressure switch has nothing to do with your current problem except the 2 wire connection.

Replying to: gonogo (May 30, 2008 8:22 am) well i was driving up a hill and when i stopped at the light and went to take off as soon as i let off the clutch and gave it gas it died and would not start. when i pulled it to a nearby parking lot i smelled burned wires. so far ive trace the fuel pump relay, replace the pump and sending unit. the only thing i havent replaced is the oil pressure switch. and from what i understand like i said before it works as a shut off for the fuel pump.

i know that on the pump there is a purple wire(to the fuel gauge) and a grey wire(to the pump). the oil pressure switch is right next to the oil filter, its sticking out so you cant miss it lol.but i think im going to replace it and see if that fixes the problem if not its one of the wires coming from the switch, i just wish i had a diagram. or knew which fuse in the fuse box works the fuel pump....anyone know?

Replying to: ohiaboy (May 30, 2008 12:11 pm) Have no information for a 93 fuses, no decal on the cover. On the later ones the pump fuse is ECMB.
