ok 03 wrx 5sp mt. my center diff/ viscous coupler is tripping out if i just ride around town its fine but say i hit the freeway for about 15-20 mins it'll start binding up on sharp turns like parking lot/space turns. when it is cool it runs calm and smooth ,but once i it gets freeway for a few(17 miles bout 20mins or so next town over at freeway speeds)it starts binding and popping when i turn at lights or parking spaces or driveways till it cools for a while. example i get in the car and start to drive to my friends house the next town over starts out smooth i get on the freeway still smooth exit and take my first turn after exiting and it pops and binds almost like its running a spool or a locker. if after i get to his house we chill in shop and piddle with some car junk for a couple of hours and i start driving home its smooth again. if i get to his house and we leave directly after i get there to go pick up a part or something it will keep binding up every corner till i let is sit and cool off. if it is binding and i go to a smooth parking lot and turn lock to lock and just idle around in a circle it will chirp the tires as it makes its circle.
so i think i have found a wrx 5speed trans that has teeth missing off of second gear but has a good viscous coupler. I'm wondering if it would be a better idea to rebuild the tranny with the blown second gear or to just pull the coupler and put it into my current trans? the guy wants 100 bucks for the blown tranny? what do the gurus think?
