Shifter/Tranny Questions

turbo1992 =ck the turbo bypass valve or hooter valve. its located just under the dstributor. pull the vacuum line off from the intake and suck on it to see if it holds vacuum. if it doesnt hold then its no good . if it does hold vacuum its good. that solved my bucking problems when letting off the gas.

Recently checked...holds vaccum.

c900s love to wear out transmission drivers. The drivers are soft and the 3 ball inner joint on the axle wears a divet in the metal giving you a vibration on acceleration. especially bad when accelerating and cornering, or basically any time the suspension or engine moves. Feels similar to a tire out of balance or a bent wheel.

I serviced the axles recently and both drivers looked good. I am thinking it may not be a bad idea to swap them side to side as many suggest. Odd thing is the vibrations come and go making me think it could be related to the belts, especially noticeable when the ac is on during acceleration. I also changed the left front wheal bearing thinking it could be worn as I had a subtle "wap wap wap" when coming to a stop. It's still there and has me puzzled. I displays no other symptoms...just an anoying "wap wap wap". Could be the caliper? Not certain but when I did the bearing everything looked pretty normal.

I am getting a bit of noise [like a vaccum loss] out of the turbo path, this along with the bucking makes me thing it may not hurt to change the valve with a new one. I'll report back.
