i have been searching for days now about crank walk and other issues to my problem.. i dont believe it is crank walk but hey i have 153 000 miles on the car with another 600 miles on the new clutch... i went through bled it a million times checked for leaks adjusted the clutch rod and checked the master cylinder and slave.. all looked okay... the issue seems to be that if im driving down town with a lot of stop signs the clutch will all of a sudden get super soft.. i dont know if it has anything to do with turning right or left just have not paid attention i guess.. also there is no clicking form the timing belt cover so that should rule out crank walk right? the clutch seems to have to be pushed in super hard to get the car to start and then when it gets soft it grabs really quick.. then today it got really soft and i shut off the car to go into the bank then i came out and started the car after pushing my foot through the floor and started it up and put it in gear and let the clutch out and it would not grab even when my foot was completely off the pedal so i put it in second gear and stalled it LOL.. then restarted it and first gear worked again... so any help please???? :cry::cry::cry::cry:
 
- Are you sure you installed the TOB and wire clip correctly?
I remember I put one in wrong once and I had similar pedal feel issues plus had no 1st, 3rd, or Reverse LOL. Dunno what else to tell you, good luck.
 
A soft clutch pedal is indicative of the fact that the hydraulic system is not developing any pressure. The resistance that one should feel when depressing the clutch pedal is the pressure plate spring force. Lack of pressure be caused by air in the system. You must have a helper operate the clutch while you observe the clutch fork travel. It should move about half an inch. Bleed the system. The master cylinder or slave cylinder could be worn out and leaking fluid. Check for wetness inside the car below the top of the pedal on the firewall. Look for wetness around the slave cylinder rubber boot.
By the way, a more technical term for "crankwalk" is excessive crankshaft thrust bearing wear. It can also be called excessive crankshaft endplay. It can be positively identified by removing the oil pan and prying the crankshft forwards and backwards. Any "play" in excess of 0.010" is bad, but should have little effect on clutch operation.
All sidewall type thrust bearings wear out eventually, just like the other mains bearings.
Having 0.015-0.025" of crankshaft endplay on a motor with 150K miles is quite normal.
I believe improper clutch operation is a major contributor to premature thrust bearing failure. There is no need ever to let your clutch out at 3500 rpm's from a full stop (launching) unless you are on a race track. Yes, it will flatten the thrust bearing side walls fairly quickly. "Popping" the clutch is no good either.
 
x2 for bleeding as I just did mine and while I didn't have an issue before, it still was an improvement.
 
then today it got really soft and i shut off the car to go into the bank then i came out and started the car after pushing my foot through the floor

Let me guess, if you own a DSM, you were most likely making a "withdrawl" from the bank.:hmm:

If you have 153kmiles on the car, I wouldn't worry about the crankwalk thing. It also happened much less in 98-99s which had a revised thrust bearing.

It has to be an issue with the hydraulic system or pedal adjustment.

You may want to replace your clutch line with a stainless one which will eliminate the accumulator found on 2gs

IIRC 6/98 is the build date around where they switched. I have seen mostly 97-98 FWD cars walk (although I have only seen 3-4 cases) and its usually between 80k-120k. My 95 took a hell of a beating for 158,XXX when I pulled it out the engine was beautiful. I think you can rule out crank walk.
