vibration

I haven't posted here in a few years been I had sold my 86, bought a 01 Cobra. I recently picked up a high mileage, abused 93 Cobra. I have been working through some issues but one that has been getting the best of me has been a vibration at 1300rpm and then again above 3500rpm. This vibration...

So i have a 1990 fox body mustang gt and i have this horrible vibration. At about 50 mph the car inst bad you can feel it just barely. But 60+ it is horrible the gear shifter is vibrating like crazy and the steering wheel just started to shake up and down and kinda all over the place. I know...

My car is a 2003 GT. The TR3650 broke, so I replaced it with a T56 Magnum about a year ago. The t56 has the following gearing: 1st 2.97, 2nd 2.10, 3rd 1.46, 4th 1.00, 5th .74, & 6th .50. Recently, the car has started to vibrate a lot at 40+mph. When the car is in 4th gear at 40 mph, a vibration...

I'm in desperate need of some help with this infernal vibration i'm getting in my car. At speeds over 75mph i get this vibration from the rear that gets worse the faster you go. By the time i hit 90mph the whole rear end and shifter is making a buzzing sound. Here's what I've tried. Rotated the...

Ok so I'm still new here, but hopefully everyone can maybe give some help. First of all the car is a 88 Gt. Basic mods, nothing extreme. I'm a high school student so even though my local shop does good work bringing it to them is not an option. I was driving on a city highway and all of a sudden...

I'll start off by saying this is my first time on forums so bare with me lol. I bought my 3rd mustang, a 89' notchback 5.0 (carb) :salute: a couple months ago. I've spent a bunch of time since I bought it correcting some engine issues. But I'm needing some opinions before I just start throwing...

Hey fellas so i droped my stang last week with some Ford Racing "B" Springs and some new poly isolators along with some UPR solid lower control arms and caster camber plates. I got everything buttoned up and it droped about 1 1/8 up front and about 3/4 in the rear. So after that i took the car...

I have a 97 cobra, I'm sure it's every gear, I feel a pretty hard vibration underneath me like if its the transmission, it might not be the trans just trying to figure this out, it starts vibrating like around 6k rpm what could this be???? I need to get it fix I'm under the impression that its...

I have been chasing down a vibration with no luck. The vibration starts at roughly 65 mph regardless of what gear im in and when i push the clutch in the vibration gets considerably worse. The vibration started shortly after the installation of a Tremec tko 600 trans. I have had the driveshaft...

Hey everyone, I have a harmonic balancer question. I'm getting this really nasty vibration/shaking in the upper RPM range. like 3500 to about 5k. Anything under that it is smooth as glass.. Would this be a harmonic balancer issue? it dosent matter what gear it seems to be RPM related.. I've...

I bought an 07 V6 convertible last year for a song, but now along with the song come some shakes. I notice a bit of a vibration in the car when driving anything over 35mph. The tires have been taken off and re-balanced taking into consideration the TPMS belted to the rim, the driveshaft is...
