#792 of 2018 S10 EXT CAB SHIMMY
Jun 10, 2005 (9:38 am)
I have a 2001 S10 that has always, always had a shimmy that is worst at 1850 RPM (about 65 MPH). I took Chevrolet to arbitration and lost as the female arbitrator agreed with Chevrolet that the truck "operates as designed.)
I just put new tires on it after 72,000 miles, and the shimmy is still there. No one I ask who drives one of these trucks (extended cab S10/GMC Sonoma) which have a 2-piece drive shaft, admits to noticing a shimmy. I tried several (11 or more) new/used, 4-cyl/6/cyl, standard/automatic, and they ALL have the shimmy. Most are worse than mine, and the worst I drove was a new '01 Sonoma 4X4. The image in the outside mirrors was not discernable due to the vibration.
Anyone else notive this?

Yes, the oil cooler lines leaking is a common occurrence on the S-10's. The problem is with the crimping of the hoses which weakens over time. It is important to fix ASAP because the hose can separate from the metal portion of the line. You would then lose all of your oil.
As for the dye test, it is not a bad idea. In my case, I had two leaks: one with the oil cooler lines and the other one through the intake manifold gasket.

What I meant was - sometimes the Belts in the tires will take a "Set" of they sit in the same location for a long period of time. There was one tire (Aramid ?? or something like that) that they took off the market due to the belts doing this -especially in the cold weather. So, I thought that since the tires we old and that he truck obviously sat for some time (as it's older with low mileage) the belts may be trying to "Steer" the car or cause wheel hop.....
I'm all ears as to what you find out .....
#795 of 2018 Broken FlywheelS
Jun 10, 2005 (2:19 pm)
I just got my '94 chevy s-10 2.2 automatic in febuary and i have already had two broken flywheels. The transmition bolts are tight and everything. When the truck starts it vibrates, could that have something to do with why they are breaking? Do you know of anything that could keep causing this to happen?

OK, here's the latest scoop. I took it in this morning for a front-end inspection. Bushings, bearings, etc looked great, but the alignment was out of spec. They adjusted it and improved all of the alignment settings, especially the caster which was the really bad. I've only driven it about 10 highway miles since then, and that was with a 40 MPH crosswind, so I couldn't tell much about the tracking...I was getting blown all over the place. I did notice that it steers better going around corners in the neighborhood. Tomorrow I'll take it out before the wind kicks up and try it on the highway.
Thanks to everybody for your ideas and the good discussion. I'll keep you posted on tomorrow's test drive.
Also, I'm still keeping an open mind about the tires being a factor in the steering. I know they look like new, but I've never driven on 7-8 year old tires that have been sitting around like this, so I don't know what to expect. My tires usually get replaced due to treadwear, or the sidewalls crack way before 7-8 years.

Well its time for an update. after doing some research on http://www.tomorrowstechnician.com/tt/tt30216.htm i discovered a bit about the crankshaft differences between 94 and 98. So, that being said, here we go again. I am locating a 97 crank to fit the 98 block and seeing if that fixes the timing problem. At the same time we are going to adjust the rear axle to get it recentered. I had bought the truck with a lowering kit (3" front lowering springs, 4" rear lowering blocks) installed already and have come to believe the rear axle has moved a half inch forward, causing the input shaft bearings to be under extreme pressure. I'll have further updates later. A simple question to end the update: As far as differences in power steering pumps from year to year, should the 98 whine or not? If not then I'll be replacing the pump with the original 94 pump.

DTC P1336 will only set if the PCM has not learned the crankshaft position system variation. The PCM only needs to learn this variation once per life cycle of the vehicle unless the crank sensor to crankshaft relationship is disturbed. Removing a part for inspection and then reinstalling the same part is considered a disturbance.
A fully warmed up engine is critical to learning the variation correctly. If a valid learn occurs, no other learns can be completed on that ignition cycle.
If the engine cuts out before the specified learn procedure engine speed or at normal fuel cut-off rpm, the PCM is not in the learn procedure mode. Review the Crankshaft Position System Variation Learning Procedure and re-enable the learn procedure. Verify that the scan tool displays Test in Progress.

hey, Joe3891 what do i do if i don't have a scan tool? Im limited to what i can use. I only have access to the basic tools. so should i pull the crankshaft positioner out and put it back, and let the truck idle until it warms up? and by the way thanks for responding to my question.

My drivers side high beam will not work. I have replaced bulbs, but still no luck. What can I do?

This is all I could find right off, I have a lot of information but my file keeping is lacking. I will look again as soon as I can, sorry about the delay.
