I need this info to order offline... between $100-150.... its $400 at the dealer. Its 2WD 4L60E tranny, and I could'nt find any stamp on the axle for a code. Help...Thanks....

#29 of 35 Even more vibrations by chunkeylover13 Nov 18, 2008 (7:11 pm)
I have a 1995 s10 4.3l CPI with around 32,000 miles on engine and 214,000 on tranny and at 1,900-2,000 RPMs I hear a vibration. It doesn't do it every time, but when it does it doesnt matter what gear. It hasn't always been like this it started a few weeks ago after I rotated my tires if that has anything to do with it. If anyone could help with this I would greatly appreciate it. Thank you.
#30 of 35 wierd ticking sound by zbkeebler Dec 03, 2008 (8:34 pm)
it almost seems like a metal on metal contact and it is throttle responsive...at first it only did it when i turned to the left...now it has progressed to the point it does it non stop when running...i have dropped the tranny and there is no sign of rubbing anywhere...sometimes when you give it gas it almost feels as if the pedal is catching slightly and it kicks just a little along with the tick...but the sound is coming from the tranny tunnel up close by the heater vent on the drivers side....   anything helps....really annoying...fed up with it...suggestions please   its a 1993 sonoma with a 4.3L, automatic

Replying to: aeunice (Oct 20, 2008 12:22 pm) Well I have a 2003 sonoma reg cab. The rear end vibrates more than it should. I did all trouble shooting I could. Changed tires, checked the drive shaft and mounts, even put light to heavy loads in the bed. The vibrating continues. Oh well. I just recline the seats a bit and then slide the seats back hard so that the headrest smashes up to the back window. That at least keeps the seats from vibrating. If anyone has a solution, please help. Replies to this message: gonogo (May 01, 2009 7:20 am)

Replying to: smatts40 (Apr 29, 2009 9:52 am) Vibration that bad should not be hard to find, put the rear on jack stands and run it in gear and see what is going on.
#33 of 35 rough shake. by py072888 Jun 15, 2009 (8:43 pm)
Grandfather has a 94 GMC Sonoma. 4.3L vortec. We rebuilt the motor about a year and a half ago. it had spun a bearing and we bought it that way. Replaced the crank and had rods cut and new bearings all around. New knock sensor. Lately he noticed that at low RPM's the motor shakes pretty rough. plug on knock sensor was broke so i replaced it. same problem. this motor has a balance shaft in it and i fear it is something to do with that. any ideas are greatly appreciated. if more info is needed please let me know. once highway speed is reached shake goes away as long as you are on throttle. if pedal is in only a little shake is at its worst. i believe timing is good. 12 degrees one way or the other i dont remember. will check it again tomorrow. is my timing off? what should it be? truck still has plenty of power. blows smoke and smells real rich. please help.
#34 of 35 More of a grinding then vibration by fatal22 Aug 08, 2009 (11:02 am)
I have a 98 s10. Its a 4 cy. 2.2 liter 5 speed. When I am driving 45 mph or above there is a horrible grinding noise coming from the passenger side. It stops when I let off the gas, and starts back up as soon as I put my foot back down. As of now, there is a 3 in drop on the truck which I am having removed because there are 17 in rims on it. There is no grinding when I brake. Also, if this helps at all, if I have my hand on the stick you can feel the vibrations of the grinding.

Replying to: aeunice (Oct 20, 2008 12:22 pm) I had a vibration problem on my 1998 S10 and it turned out to be the driveshafts. After replacing the U-joints I still had a bad vibration at certain speeds. Had to take it to a driveshaft repair shop and have the tubes replaced for $220. Now it drives smooth.
