1991 Notchback W/3:73

I Had 3:73's From Ford Put In My Car With All New Clutches An I Drove It The Day I Got It Back And 1st Thru 3rd Pulles Great But 4th & 5th I Get A Shimer Thru The Shifter And A Vibaration Throughout The Whole Car. On The Pass. Side I Hear A Whine And I'm Not A Rearend Man So Maybe Someone Here Can Give Me An Idea On What May Be My Problem. By The Way All Bearing Was Replaced But I Didn't Have My Axle Bearings Replaced On Either Side. ( Please Help My Second Wife Because If My Current Wife Leave Me I Need My Stang :second Wife: To Run Great So I Can Release Some Stress Lol Lol ) Help

Chances are it's your driveshaft. Do you get a vibaration in 4th and 5th when the clutch in engaged? Bolting up a nice alum driveshaft should take care of any annoying harmonic vibrations.

Engaged Or Disengaged I'll Try A New One Thanks

i changed the u joints and most of the vib went away but now i hear a roar about 100 to 120 and it is coming from all over help me once again thanks

Cab you be more specific?

Its Just Like A Roar And When I Come Off The Gas It Gets Worst Before It Smooths Out I Know Its Not Much Help But Thats It I Know Thats Not Alot Better But

And Can You Please Stop Puting Caps On The First Letter Of Every Word? Thanks.

Sounds to me like someone did not shim something properly here. Definitely take it back and have em check it out. Where was it done at?

It was done at a great local tranny and gear shop i've been dealing with this shop a long time. ( sorry about the caps & but this is for the people that has help for me & not peole that just want to be a pain in my side)

Mine roared exactly like that until I put in the aluminum driveshaft.
