95 with annoying NVH (noise, vibration, harshness)
So the question after the long story is, has anyone successfully used hose clamps to balance their drive shaft?
Runs good till about 30 m.p.h. then it starts shaking. Smooths out around 50. It'll do it under acceleration, cruising, and to a lesser extent coasting. I put in new Mercon V trans fluid including the torque converter. The spark plugs and wires had about two years on them so I replace them, with Motorcraft parts. It had been four years so I picked up a spare set of rims, got two new tires, tried them on the front wheels and then on the back wheels. Problem persists. Put it up on jackstands with it in drive and noticed a lot of wobble at the front of the driveshaft. Pushed up on the transmission and there is no play with the crossmember. I don't think it's U-joints because it doesn't clunk when putting into drive or reverse. I've read about the problems with the two-piece driveshaft and am guessing that's the problem. I'm not the only one who drives it but I don't think it's been damaged. Do these driveshafts just eventually "go"?
I'd like to try the hose clamps next... has anyone done that where it smoothed out the vibration? Car is a LX with 189,000, 4.6, automatic, no performance mods, and original exhaust.
