Tracking question for 75 & ZT

[TigerAde]

Morning guys, Right after a failed front wishbone due to U/S ball joint was replaced i had my car 4 wheel aligned.

Round the town the car is fine, but at speed on the motorway which is where i do most of my driving it's tramlining like mad and a few times i've nearly hit the car next to me.

I've rang the garage back to get it looked at asap but when i said it drove better before i don't think it went down well, lol.

Anyway, i have an MG ZT deisel with 18" Gridspokes and i've noticed on the print out on form the settings are for a R75.

I would think they should be different settings :shrug:

When i had chronic tramlining on a Mini it was because the tyres were low on tread, quite alarming but cured by fitting better tyres.

My 75 is doing this too, now it's on Serpents, and it's a 75. It's absolutely ruining my enjoyment of the car. I've even put a pair of new Dunlop Sportmaxxes on the front, and they've made no difference, other than give me reduced levels of road noise.

Here's the specs for comparison.

Many thanks T-Cut, is this information from Rover etc?

Hi all,

Having seen the above, including the settings table, I thought the 4 wheel alignment had to be done with a full tank of fuel, even though the table states "unladen".

[TigerAde]

At the time mine was over 3/4 full, i beleive that's the way it souhld be set from reading other posts

MGR's definition of unladen/kerb weight is the car without occupants and the fuel tank 90% full.

Yes, it's from the authorised Workshop Manual.

Go to somewhere like ATS and have a computerised wheel alignment as you can get printouts of before and after.

[TigerAde]

It wasn't ATS I went to but I do have a print out of before and after.

Post a scan of the print-out so we can check if the settings are in spec for the ZT.

It could just be that the tyres have worn unevenly and correcting the problem has highlighted the issue.

It might be worth swapping the fronts for the rears and see if that helps.
