Like smorris_12, I did my own wheel alignment after changing the front wishbones and inserting PU lolipop bushes. I could physically see the front wheels were toeing out considerably.
At first, lying on my back under the car, I almost gave up on trying to undo the solid trackrod lock nuts, but I persevered and used plenty of Plusgas. This is really amazing stuff and after about 20 mins of soaking, they came loose.
It is quite enjoyable trying to get the front alignment correct using an adjustable metal measuring rod between the rim inner edges (and an adjustable spanner and mole grips). It is like a puzzle that you have to crack. A bit time consuming though.
Essentially:
1. Get both wheel rims equidistant - mark the inner track rods with tippex and rotate them evenly in or out on both sides. Keep comparing the gap between the front of the rims and the rear of the rims with the adjustable bar.
2. Take it for a test drive down the middle of a straight road.
3. If the steering wheel is off-centre to the left, for example, then you need to move both front wheels equally slightly to the left.
4. Take it for a test drive
5. If the car pulls slightly left, for example, that means one of the wheels is pointing a little too far left, so try moving the front left wheel in a tad or the front right out a tad.
6. Repeat all the above until it's perfect and feel smug.
(This all assumes the rear end is about right.)
or take it to a tyre shop and listen to them hammering and swearing !
