[Healeys] "SS" aka--scuttle shake

Thu Jul 8 17:22:47 MDT 2021

An E Type is a full unibody aft of the firewall and its sills/rockers form what is effectively a tube chassis.  The front subframe IS a tube chassis.  

The sill/tubes are enormous, much like you would see in a serious race car – GT40, Porsche 917, etc.  The front subframe IS what you would see on any current race car.  

Very little comparison between the way an E-Type is engineered and constructed compared to a Healey. 

I own both, I love both, but there is no comparisons to be made between the two.   Apples and Coconuts.

FWIW, our ‘65 Mustang convertible had ‘scuttle shake’ as bad as my Healeys. My dad was a factory rep for Ford back then, and he said they all did.

Hagerty magazine has a big write-up on E-Types this month and news to me was that the Jag had a partially tubular chassis, which is likely stiffer than Healeys.’

Well, first of all the structures are different between the E-type and the BJ8.  The purpose of the structural mod to the firewall is to stiffen it to increase its natural vibration frequency.  I did that mod and noticed the difference, but it didn’t remove all of the shake.  Allen Hendrix did his magic by balancing and truing the wheels and shaving the tires.  It removed almost all of the shake, and balancing the drums did the rest.  I consider myself lucky to live close enough to Allen that I can take the car to him when necessary.

I have no scuttle shake on my 66 E-Type OTS and it is smooth as silk at all speeds. Why would a Healey or any car be any different? If this was a function of the tires, would'nt we see tires being shaved on many different cars? I have this strange suspicion it is unique to the Healey.

I had the tires shaved and balanced and the tech marked each tire as to the position the car.  The best were on the front right left and the worst were rear right and left.  Did not balance brake drums or anything else.  Now only a little shake which is acceptable.  Best $200 I ever spent on my BJ8, along with the new Michelin 180 tires which cost a little more.

Hard to find a garage which has the equipment.  You need to do an in-depth search for Shaving Tires Near Me.  Fortunately, I found a great guy with the original equipment 2 hours drive across the state of Florida.  Note, you may find garages listed that only have equipment for Truck Tires.

Agreed, I had the tires shaved and the rear brake drums balanced - now no scuttle shake.

Second------for the years I have had this car, I have hated the dreaded scuttle shake.  I have balanced all wheels--even added the scuttle shake "mod"  (cross beams on the inner body, behind the engine) and had the rear drums balanced locally.  All to no avail-----between 55 and 65 there is comes again!!  The drive was wonderful all the while as long as I drove slower or faster than these speeds.

What to do------what to do???

Any thoughts would be appreciated.
