I know there are many posts about vibration in drive train and steering and most of the responses point to wheel balance, bent wheels or out of round tire or wheel.

I recently experienced a vibration at 70-75 mph which I feel primarily in the steering wheel. My MY2000 coupe has about 74000 miles on it. I have eliminated any probable cause with wheel balance, tires or wheels. My engine mounts are good and the Vee mounts look OK. I looked at the Jurid coupler and can see cracks in the rubber disc, my question is has anyone had a vibration while driving and have it corrected by replacing the jurid coupler?

Thanks in advance for any feed back on this issue.

Hey John I don't recognize jurid, is there another name?

 

Have not had that here, but if it's cracked, I might fix it. Appears to be around $50-$160 on SNG Barratt depending on which one you choose (CBC8996).

Just curious, however, but does she sit much? Two of my three had a vibration at this speed when I first bought them which almost completely ironed itself out driving @80mph for 3-4 hours (had to bring them back), and the tendency completely ironed itself out with new tires. Have you done a road force balance?

 

JNelso,

Sorry never had a problem with the drive shaft coupler before. As you say, vibrations only at speed are generally caused by wheels and tyres.

Are you sure it's the Jurid Coupler? Post a picture of what you see. If it is nackered, there's a great thread by Aholbro1 on the R&R of this part with good pictures. Link below.

Jnelso,
From what you describe, I think it is the front brake rotor discs out of balance. It's unusual but not unheard of.
Sometimes, when very hot, they can warp and then wear unevenly - ultimately becoming imbalanced.
It would explain the symptoms you describe....
