please please please dont be crankwalk k well here goes:
whenever im in first and turning left, my car studders like a MoFo, sure sign of crankwalk right? but it only does it when im going under 5mph and only when its turned left to its very max (works just fine when doing a normal left turn), the clutch pedal will also be free to move anywhere.. i thought a sign of crankwalk was that it would only come up so far during the turn. it also does it in reverse no matter what way im turning, even when im going straight back too. also, just starting this morning, when i turn my car on i get this very nice LOUD grinding noise that lasts about 3-5 seconds if i just let it idle (not starter). then tonight, the car did all that usual crap, then i got to the first stop sign, and slowly started accelerating and i got the loud grinding noise until i got up to around 10mph, then was normal driving home. ever since i got my car about a year and a half ago, the 1st and reverse gear have always been crappy, slowly getting worse too. it was just like the synchro's were bad in those (prob just adjustment though). the car's got 113k miles, with UICP/LICP, BOV and exhaust, so the clutch shouldnt be slipping much anyway..
any help is VERY MUCH APPRECIATED!!
