Rear Axle Hub/Brake Problems Again!

Posted on by

We don’t seem to be able to escape our problems with the fitment of the rear axle hubs and brake drums. A thorough accounting of the issues we faced were first documented in several videos included in an earlier post:https://valvechatter.com/?p=13569

We thought we had conquered the problems we had encountered with the hub rubbing the axle flange and with the brake drum rubbing against the brake backplate, but upon installing the road wheels and tires we discovered that all had not been corrected! 

The wheel on the left side of the car turned freely but on the right side we found that despite the hub nuts being tightened and torqued to 38 ft. lbs. as directed in the maintenance manual, the wheel and tire wobbled back and forth. It is a little hard to tell but it can be seen in the beginning of the Bugeye Restoration Video Episode Ninety-two. We then tried a pair of brand new Moss Classic Gold brake drums that we had on hand.

Unfortunately, the new drums rubbed against the backplates just ever so slightly. We visited our friend, Randy Forbes, and he graciously set up his milling machine to remove .0075″ from the back side of each brake drum. We then mounted them on the car and found that we had eliminated the rubbing against the brake back plates, but we still had the dreaded wobble on the RH wheel.

We removed the RH axle half-shaft, bent back the locking tab washer and tightened the hub nut to 145 ft lbs. This actually turned the nut very little but it was sufficient to eliminate the wheel wobble. Not really sure about the mechanics of all of this but we will take it and move on!

All of this trial and error is shown in the Bugeye Restoration Episode Ninety-two video.

We will now machine the edges of the drums and see if we can end up with a fully operational axle assembly. Stay tuned….

 

 

 

 

 

Wheels & Tires

The Original Tires and Wheels

The wheels were Dunlop 15” 48 spoke center-lock wire wheels painted silver-grey secured with a two-eared chromed bronze knock-off. The car was fitted with Dunlop Roadspeed RS4 tubed black-wall bias ply tires.

Tire and Wheel Modifications

I decided to use Dayton chrome/stainless wire wheels supplied by Hendrix Wire Wheel. The selected tires were Michelin 175 x 15″ ZX. Alan Hendrix and Jerry Anderson were both very helpful with the purchase and with follow up questions.

Tires and Wheels

Fast forward to August 2015. I am way overdue to replace my Michelin ZXs. They still look great but they have surpassed their useful life by a considerable number of years! The sad news is that the ZXs are no longer available. That is a shame as I really liked the way they looked and performed. Following a fair amount of research, I have concluded that the Michelin XAS 180 HR15 is the best tire to replace my ZXs. Many Healey driver’s have switched to Vredestein Sprint Classics, but I favor the Michelin tire. The XAS has a slightly larger diameter: I believe 26.7″ versus the ZX 26.” The XAS has asymmetric treads favored for a smooth nice ride with good traction. There are a couple of downsides. Unfortunately these tires are $260 each plus another $27 for a tube for each tire. The ZXs were tubeless! My other concern is that the slightly larger tire may not fit in the boot. As a consequence, I have decided to take Allen Hendrix’s advice and go with a smaller 165 Nexen tire ($100) as a spare. This should work fine. On the off chance that I actually need the spare, it won’t be on the car for long.

So I ordered the XAS tires from Coker Tire in Chattanooga, TN and had them drop shipped to Allen Hendrix. Next week the wheels and ZXs go to Hendrix Wire Wheel to have the wheels checked, tires mounted and trued and then shipped back to me.
