MG TD TF 1500 - LUG CENTRIC BALANCING

In my search to eliminate the 50-55 mph wheel wobble that so many TDs have,(and many do not) I have devised a simple way to have the wheels/tires LUG CENTRIC balanced rather than wheel hub centric balanced.
I stripped the bearings and spacers out of a spare TD front drum/hub, and it mounts on a regular spin balancer shaft using a cone on each side. The cones go against the edges where the inner and outer bearings would sit, so it should be centered as it would rotate on the car.
The only problem is that each tire/wheel has to be mounted and dismounted with the 5 lug nuts which takes a bit of extra time.
I just got (5) new tires mounted and I should find out what a difference it makes this weekend.

This is what I'm thinking about, on the car wheel balancer. You can find them on occasion fairly reasonable. PJ

Hi Steve,

before you go to that trouble, make sure you balance the hub first. Those large hub/drums are notorious for being out of balance.

You would loose any advantage on your balancing if you ignore the actual hub unit.

DLD, Yes,, we balanced the hub first,, Hopefully I'll get the car on the road this afternoon,,

PAUL,
I don't think that type will fit on the rear wheels, but I guess they can be switched with the fronts,,

Your right Steve, I was thinking of disk wheels anyway, wrong setup for wires. PJ

Steve and DLD -

A newbee question:

How do you balance the hubs?
Can I do it on the car?

Thanks,

Lonnie,
Front hubs have to be without bearings, they should fit a regular balancer using two "cones". Tape the weights on. I didn't do the rears, but I think two "cones" would work there also.

Thanks Steve

Wish I had known that before I replaced the wheel bearings.

Have you checked your wheels for run out ? Not being round is a common source of vibration. Just because it only shows up at a certain speed may just be something to do with the particular harmonics of the vibrations caused by the wheels not being lateral and vertically within tolerance...

dave,
That's where my whole problem started,, I've gone through a few places that said they could straighten them, but they didn't do a good job.
My LUG CENTRIC idea for balancing the new tires using a front wheel drum on the balancer worked a lot better !! now just a very very minor "shimmy" about 55mph,, then it smoooths out again over that.
