VIBRATION !,Any ideas?

[AnalogVX]

If the wreck pulled the drive shaft out, maybe the drive shaft is bent or out of balance? Maybe U-joint? Or bearings?

*edit* just re-read your post to see you already replaced the driveshaft.

Just becaue a part is "new" doesn't mean it is straight or in balance. You might still want to have the drive shaft and other new parts checked. I've had many new parts that are bad from the box.

Let us know how you made out after the visit to the shop...dying to know what they find...if anything.

The saga continues, didn't get to talk to the mech. after work...all I know is,
they ordered more parts & when they come in, they'll call me.
I'll keep ya posted on new progress as it happens...I hope.

One more thing to check - the exhaust. The flange is right above the cross member - the impact may have dropped it slightly, causing the flange to lightly touch the crossmember - this would be most noticeable during WOT as the engine torques. Also, the front part of the exhaust on the right side gets very close to the right torsion bar and could be doing the same thing. It's very tight under there and the mere touch of an engine part to a body or suspension part could be causing the vibration (when it's really hitting you'll hear a clanking type noise, but if it's just touching it will transfer the engine vibration). Just something to consider.

John,
Thanks for the input,I've been under there with the mech. quite a bit lately & the exhaust looks like it's all good.The vibration starts at about 20 or so mph.as barely perceptible & gets more pronounced when more speed is added. When going 60 mph. you can feel it & hear it, but when I shift from drive into 3rd, the rpm. increases but the frequency of the vibe remains constant.We're looking at everything driveline related. The sound isn't like a bearing rumble, it's less noticeable.
One thing that I can't comprehend is when VX & tree made contact, R/R tire got a hole in the sidewall & all the energy was transfered through the wheel into the axle & axle housing. The axle & housing were bent but the rim is straight,a testament to the strength of suzu rims I guess. Yes, I am sure the rim is straight because I had the tire removed & the rim put on the balancer at the tirestore where I used to work.There was almost no runout (maybe 1/64),not enough to cause this much vibe.
Thanks again to all who have taken the time to respond, Ldub

Well, finally get to drive VIBE FREE !...turned out to be the coupler between the output shaft & the first (going front to back) U-joint.Glad that's over, now the weather is warming up & I've got much wrenching to do. (Piaa 1000's,
new HID wiring harness from Tone so HID's will stay on w/ hi beams,Borla muffler,new Thule Xpedition roof rack,fuel filter, etc.)
Thanks again to all who helped with ideas/suggestions & Happy Easter, Ldub
