Very loud popping after accelerating
I'm at loss... I'm no newb to fixing problems, I've destroyed enough things in my firebird, swapped motors, transmissions, rear ends, suspension etc... but this has me and all my friends stumped. I'd be very grateful if anyone could suggest something I haven't thought of yet so thanks in advance for any suggestions...
when accelerating at a decent pace (half throttle maybe? maybe a bit more) you can hear VERY loud popping from the front, Steering wheel shakes a little as well. As if something was binding, possibly slipping and grabbing. It's a mechanical sound such as gears slipping or something along those lines. It's coming from the front, either right dead center or possibly more on the drivers side of the car. Once the car is rolling it doens't do it again, just the initial acceleration overcomes something mechanical and causes it to pop. (makes no difference if turning or going straight).
so far I've replaced... (some stuff for other reasons, but at least they are new)
WHOLE CV half-shafts, both left and right side (so both inner/outer joints and shafts)
did a nice tune-up
engine runs great
transmission runs fine other than sometimes when downshifting at higher speeds the car shakes a little, but all gears work and don't seem to slip any (fluid smells good too and is nice and red).
my ideas: while changing the dr. side cv half shaft we were unable to pull the inner side of the inner joint off the transmission axle. It's just a hunk of metal sitting right on the axles splines. After using a 4 foot prybar and two people we gave up and basically left it there, disassembled the new cv half shaft and just slipped it into that metal end. At first I thought maybe the splines on that drive axle are shot and that side wheel is "slipping", but then I would think the half shaft would come right off or I'd at least see metal shavings aorund that area. It's just "frozen" stuck and nothing will make it move.I have not yet tried marking both the shaft and inner joint with a marker to see if they truly are slipping, but I don't think they are.
any ideas ??? car's not worth taking it somewhere to get it fixed, Especially when I'm leaning to the conclusion that it's transmission related even though I fail to see how that's possible when there are no other transmission problem going on.
It's a 1995 Intrepid with the 3.3L engine btw and obviously automatic transmission.
