Pulling the battery cable off when the truck is running is a quick way to find out what a voltage spike can do to a PCM...

On a truck this old that is showing intermittent charging system concerns, I would consider the alternator brushes as a prime suspect..... As the brushes wear down, spring pressure is lost and, if the slip rings are out of round, the brushes get pushed back in the holder and can't follow the rings.... FWIW, in the case of worn alternators, few shops do anything less than install a rebuilt alternator.... The reasons are many and the thinking is sound.....

If your engine revs high in the AM, I would first consider an IAC concern.... for the stalling, I can only suggest making sure that the basics are good (base engine - tune up - filters - etc.) and to check and see if there are any codes in memory that might point the way.

i am thinking of taking it to the shop i just would like to be armed with some info, maybe hook it up to the machine thanks for the advice

damn the bearing or the caliper started scraping today on the drivers side...i am thinking its the caliper that siezed, and hoping this is the case, she only makes noise when i am moving and the noise goes away when i hit the brake...but not gone when braking. so i guess its up at six tomorrow to get her up, tires off oh joy hope its not raining

Be sure to select a shop based on their competency rather than their price.... A cheap but incompetent shop is a gamble and can weind up costong much more in the long run...

Good luck with the noise...

i removed the dust cap and the bearings were nice and clean no grease inside, too bad. good thing i only ran a couple blocks then turned right around after they started making noise. did both outer bearing repacks on the front she is fine. too bad i have to work outside, i would have pulled everything off and done the inner bearing as well, its so hard to keep clean. i left it for later but priority now. preventative maintanance.

also yeah, i took my driveshaft into get the hanger bearing pressed in, i decided that i may as well have the bad rear U joint replaced. the guy asked me what side was the rear, being in a hurry i have no time for nonsense, it certainly did not inspire confidence...but it was the closest shop and they were open earlier.

i get all the work that i cannot do myself or just cant figure out at a respectable shop here in town. everyone needs a good honest competent go to guy, no matter how good you are eh? i did some work on his house, i was ahead of him 950, then i got some major work done on my truck, i had to give all the money back plus 950 hehehe...too bad his new house doesnt need any work i know the number it would cost all ready.

The outer bearing on the front is "small potatoes".... this bearing is a "guide" bearing... it is the inner bearing (if all else is stock) that carries the bulk of the load....

I assume that brake pads and rotors are good and that the caliper mounting hardware is all in place?

yeah they are in good shape, but in the next month i wanted to put it all up and have all the wheels off, do what needs to be done under there, i noticed some weather cracking in my front drivers side brake hose now i am wondering what else is going on...time to check it all out. am going to pull the hubs off somewhere clean and grease that puppy right up.
