1991 Fox convertible shakes

Blueinfan · Jun 18, 2024

Hi All,
I have an issue with my 1991 Fox Convertible. It started shaking on a roadtrip to a meet. My friend noticed that the passenger side motor mount was broken. So I replaced that today n checked the driver side n all tightened to specs. Took it for a spin n still shakes like crazy. The engine is stock. Am I missing something? It never shakes like a Harley Davison motorcycle before. Forgot to mention that it shackles leaving a complete stop n when it shifts to second. Seems like something is easier loose or broken.

I sounds like your hub and bearings are bad.

Jack the car up, grab hold of the tire top and bottom and try to "wiggle" it. If there's movement then pull it all apart and change the hub.

WOW! Everything on car is new. O well. I will have to check tomorrow. Thank you! I appreciate the help. The light is done! Thank you on that too!

It may have been torqued incorrectly if it's all new. Worth checking.... I don't recall off the top of my head, what the torque vales are but there's a seating torque and operating torque.

Does it shake while stationary?

It’s hard to tell from your post if this is an engine shake or driveline.

Yes, much more info needed...
Does is shake in neutral when you rev up the engine when you are stopped?
Does it shake when you are driving down the road and put the car in neutral and coast?
Does it shake when its only in gear and you are driving or when you start from a stop?

HEY, thats why women like to ride on the back of Harleys..... Its the vibration.....

Mustang5L5 · Jun 19, 2024

Need more info.

Possible this is a misfire and not vibration.

Noobz347 · Jun 19, 2024

Uh... yeah...

Disregard what I posted above. For some reason, I interpreted it as a brake caliper bracket broken.

Dunno where I got that idea

The cars shakes when parked, the shaking gets worse as I’m driving n the car is in first gear. Once the car shifts to 2nd the car still shakes but not as bad. Checked all cylinders n they are sparking.

Check the harmonic balancer.

Well. Well I found the problem. Broken balancer. Rubber is coming out the top. That’s what broke my motor mounts.

What’s the best balancer out there? Nothing fancy n only for street use.

AeroCoupe · Jun 20, 2024

This one is a good read with a lot of brands and varying opinions on them.

doing harmonic balancer for first time

doing the harmonic balancer for the first time and I think I have the wrong install kit it's a little pulley kit from harbor freight and now I'm kinda trapped cause rookie me has messed up everything I touch on this 91 gt and the front end is up in the air should the car be on the ground so it...

I’ve been using a stock replacement power bond pb1084n with good results.

Looks like the outer ring has slipped forward too

I would just use whatever brand AutoZone sells me that has a lifetime warranty

AeroCoupe · Jun 23, 2024

Just me but I’m not one to buy a crappy part just because it has a lifetime warranty that and the work to replace the balancer isn’t just swapping a radiator cap.

Get a good balancer like a power bond or better and call it done.
