    Thats is sounding to me like your bringing your RPM's up in stop and go traffic which has everything torquing in one direction. Then when u let off the throttle the engine slows but the inertia of the chassis keeps it going forward. What your feeling is the driveline bouncing back and forth to slow the chassis to the engine. Every non brand newly built car will do that. The only way to completely stop that is replace EVERYTHING in your driveline. U joints, CV's, trans, T case, everything. As time goes on, those parts wear down and become sloppy engaging. Meaning there is a gap in there which is where the "bucking" feeling will come from. You tend to get that less in a FWD as there are less parts to get lose, but RWD is the most noticeable. Normally its exaggerated by worn U joints in RWD vehicles. Its "normal" in a way.

    ^ that's about damn right. the first time I drove my talon was thinking like i was driving an old truck. I got a lot smoother over time, but it's just me babying it.

    (...course, I'm cheating here since I learned clutch on a Massey Fergerson Model A, Right Hand Drive tractor, left hand shift, hand throttle and all mechanical clutch...all at the tender age of 8 yrs old...had to actually stand on the clutch pedal and work the gas while I let the clutch out. Killed it many times until I got the hang of hitting that sweet spot so I can get the tractor to move without killing the motor. After I got that down, it was a nothing to drive that tractor..)

    Put the OP on a big ol' John Deere dual lug wheel tractor pulling a 6 bottom plow set with full manual clutch-no hydraulics-and hand throttle... and he'll learn clutch real quick on how not to do any bouncing.

    Once you master that, then you can drive any clutch car or pickup/truck without any jerks.

    Trick with driving clutch is to find the sweet spot when you let off the gas and dump the clutch where you can shift in stop and go traffic and feel that you're driving an automatic.

    also, on this "decelerating bucking syndrom," I've found it goes away if you keep your foot slightly on the pedal (open the Tb just slightly) and still slow down of course.

    you will only wear out your clutch on a down shift if you slip it real slow. if you put in the clutch, break a little bit to around the desiered RPM and then let out the clutch normally (trying not to slip it) it will not wear out the clutch. if your in 3rd at 4k rpm and downshift to 2nd at 6000 rpm or what ever of course that will be rough.... AND wear the clutch excessively; because the clutch ends up helping the motor slow down due to the clutch disk rubbing on the flywheel, slowing down rotation until you accelerate


    why in the world would you gas with the clutch in at all BEFORE you shift??WTF

    more like coast through (in neutral, clutch out) then clutch IN, shift, clutch OUT/ gas on.

    you guys and your F&F double clutching

    I kind of have that too. I have a lot of gear lash in the rear differential, so from accelerate to decelerate the car will almost buck in stop and go traffic when I stay pin 1st gear. The transmission and transfer case have both been replaced so now it's just the rear left. If you put the car on a lift and put it in neutral, parking brake off, you can turn the drive shaft about 5 to 7 minutes worth....if you think of it as a clock.

    carrier bearings and bushings, and rear diff solid bushings.:thumb:

    dont know what to tell you about the drive shaft play.. not sure if thats normal or not. i would think if you have an LSD that would be normal as it allows for some movement. i have bucking when rolling about 5 mph in 1st same thing. its bushings and carrier bearings man.
