My knee is sore after that drive.

I decided to get out early in the am before traffic last weekend and try to practice with the truck. I still have to get enough confidence to go get it weighed. 

My plan was to head out north Livermore into the country roads, giving me a chance to open it up without being on the highway. 

I didn't make it, right as I stopped and turned right onto north Livermore from portola the gas pedal fell behind to the floor and the gas pedal lever that goes through the firewall now sets higher than the pedal actually reaches. I limped the truck into the neighborhood just to the right; I couldn't find a reason for it; but the gas pedal shaft will no longer rest behind the pedal. But works and goes all the way to the floor. 

So I got back in and I drove the truck by just keeping the nub of the gas pedal shaft under control with the bottom of my shoe. I was getting the hang of it; started a couple times from a dead stop fairly elegantly. Then I got brave and decided I had annoyed this set of neighbors enough I should head back home. The north Livermore back country would have to wait until I had a  less than lethal gas pedal.

Just as I get to the light to turn left it turns red, ... Dammit. Now I have traffic behind me and I get to be first into the intersection when the light changes. The light changes, I start out good, gas is strong, clutch easing out, not covering enough ground, ... Damn I didn't realize this intersection was this big, more gas less clutch, a herking-jerking we go, I'm trying to find a position in the clutch to ease the jerking, I don't dare let up all the way, so i decide more gas, HOLY MOLY the truck didn't like that! the whole truck starts hopping like it's a seal out of water, the gearshift begins jackhammering me in the knee punishing me for my overzealous application of fuel. I finally get the beast  under control and now its moving in a straight line; people flying past me on the left. Most of them weren't mad, most of them I think were just bewildered from the show they had just witnessed and more than anything else just wanted to be farther away from it of it in case it were to happen again. 

Rubbing my knee, ... That'll probably leave a mark... I'm on a straightaway doing 35 in 4th I realize the diff must be in low; I pull the lever to switch, no sound no change; let all the way off the gas; no change. I push it in; no sound no change. So it appears the diff is stuck in low; at least that explains why I cant get to highway speeds. I repeatedly tried to change it, clutch in, Clutch out, nothing seemed to work; and I've heard it work. In my second trip out.  But nothing doin this time around. 

My short list of suspects is that I'm either not generating enough vacuum, I have a vacuum leak, the fluid leak at the diff may be a cause, or that part of the diff has decided it's on vacation until this new jerk learns how to drive it nicely. 

Oh forgot the best part, pulling it out of the parking spot I ripped off the left mirror this time. So I'm 2 for 2, I ripped off the right last time, it's costing me $16 to unpark my own vehicle each time I want to use it. $16 = cheapo head mirror replacement from kragen. I asked the manager if she would kindly keep an eye on the inventory and order some more when she gets low 'cause I'd be back...
