Re: New TA safely home...

Looks good John, hopping about and oversteer points to the rear springs being to stiff.
Regards Mel.

Re: New TA safely home...

Mel,

What rear springs do you have on your TA? I have GT springs and it still bottoms out when loaded up with two people and a full tank of fuel?

Another cause could be too much pressure in the rear tyres - I run with 24-26 psi in mine.

Cheers
Jeremy

Re: New TA safely home...

Are you running MGB rear springs? My TA is Marina based and the rear end is very smooth, specially since I had a pair of new ones built by a guy on Ebay.

I have forgotten his name, but he is very accomodating. Maybe he does MGB springs. He will add or reduce leaves, soften or harden them. Maybe you can find contact details on there.Will Marina springs fit on the MGB axle? Mine are two leaves, I think MGB are more.

Re: New TA safely home...

I don't have a TA Jeremy.

Ron, do you know if there is much difference in the weight of the two axles?
What the springs do is balance out the sprung to unsprung weight {as in the vertical acceleration of the wheel and axle). A good spring manufacturer should be able to calculate your requirements.

Re: New TA safely home...

Have been out and about in the TA (cold permitting, brrr) and the hoppity back end seems to be settling down a bit. A check through the old m.o.t. certificates shows that I've taken it as far in the past couple of days as it has been in the previous couple of years, needs a bit of driving methinks.
A few years back I had an old American pick up truck which behaved in a similar manner. I removed the rear springs and dis-assembled them, before they went back together I ground down any nasty wear ridges and the sharp ends of the leaves, a good coating of grease on re-assembly and the transformation in ride quality was huge.

Re: New TA safely home...

The MGB rear springs are supposed to have rubber leaves between the spring steel leaves and not be lubricated in any way.

However I do find that a drop of oil every now and again does wonders for the ride quality.

From what you say I would look at the tyres - sounds like you are wearing through the hard outer bits and getting more grip - these cars certainly need to be used.

Cheers
