I hope it cures your little problem.  I will be getting my 'shaft balanced this spring (no not that shaft the one on my car).

I had a long talk with the boss at the drive shaft place,and he said when you change gears,it can cause the vibration issue.He said he'd bet this will fix the problem,considering how the vibration persisted even through all of the parts that were changed.Also,as I may have already said,he said an aluminum drive shaft doesn't transmit the vibration in the drivetrain like a steel shaft will.I'll take his word for it,I'm not a specialist when it comes to this driveshaft issue.Only one way to find out.Grab a Crown Vic drive shaft and send it to them.

I'm watching this closely because my vibration issue sounds identical to yours.  So what year Crown Vic?  Any of the newer body style ones work?

I got it from a newer model Cop car.Not sure what year exactly.I didn't care,the driveshaft was a freebie.The thing is a lot longer than ours,but weighs a LOT less (apparently.....it's aluminum).I measured the width of the Sport's DS and i was 3 inches,the Crown Vic is 3.5 inches.I am not scared to have a good,happy cry if the vibration disappears.LOL.

I pulled a transmission from a '94 CV, it had the alum. shaft, but, it was a police unit. Not sure if the civvie CV's had them or not.

If Pinto was here, he'd tell us for sure, since he was apparently an expert on CV's, TC's, AMC's, and fawk-all else...

Vinnie, I hope this cures what ails ya, nobody likes a shaky shaft, lmao ;)

No shaky is a good thing.LOL.I got my DS from a cop car as well.I'm staying as optimistic as I can hoping this fixes the problem.It really would only take a couple of hours to polish it when it gets here.LOL.

jack up one side under the frame and run the car at about
35-40 mph to diagnose which side the shake is coming from..repeat this with the other side..let me know


I must be reading this wrong. If you jack up one side under the frame, that would leave the other rear wheel on the ground, and running the car in gear like that seems like an accident waiting to happen. What am I missing?

It would be bad if you have traction Lock...like the Sport.

Exactly what I was thinking. Even with an open end, it might be okay for one side, but switch to the other and look out!

:D

Hopefully the DS will be here tomorrow and I'll install it asap and we'll have some answers.

Is the vibration continuous or have a 'cycle' to it?

Haven't you changed the rearend at some time on the sport? I had a vehicle once that had a cycling vibration to it. Changed the rearend and it was cured. Hopefully it will be the driveshaft, but with it being noticed at certain speeds you never know.

It's continuous.The reason I don't think it's the DS is because with the 2.73's,all was fine.With the 3.55's,the vibration came around 65 or so.With the 3.73's,it came about 45-50.SO,I think the vibrations are caused by the drive shaft not handling the new (different) gears.NOW,that whole thought of mine is coming from no-where of course.basically a guess.LOL.

I'm anxious to hear how you make out. I've had a similar vibration in my Cougar. I was thinking it was the driveshaft, but I haven't taken the time to track down another one and find a place to balance it.

Hopefully today I'll have the DS.It may be next week,but I hope not.Oklahoma City washiznit really hard with snow and ice (that's where the company is that did the DS for me),and over 165,000 are without power.The selfish side of me want the DS now,regardless of weather.LOL.

wheel balance

Reply #74 –
if your wheels are not hubcentric, they should be balanced off of the
lug holes(most tire stores that do custom wheels have this adapter)
bolt 1 up, have the car on jack stands (put nuts on the other side
drum as to not lose the drum) and run the car up to 35 mph...if no
shake, add the other wheel and repeat process. do not let wheel hang on studs and draw wheel up to seats(sit on your butt and center first) all done by hand. you should do this also before adding
the tires with the driveline out to eliminate rear end. pinion angle is
also important for lowered cars (the guages are cheap)most quality
wheel companies have this installation procedure in the box if anyone
cared to read them. check the lug seats if wheels are used as it easy to gall new seats in the lug holes when using impact tools. if the lug seats are bad, balancing all day long from the center hole will
not help. let me know
