What the General said! ^^^^^^If it still wanders all over the road then it could be worth checking your front shocks, all the ball joints in the steering system and also the bushes on the front suspension. Something else that causes a bit of wandering is weak rear springs...........
Sounds like a plan! Also worth checking the steering box mounting bolts and the little alloy spider-spacer thing between the steering box and chassis rail as these have a nasty habit of breaking, especially if the steering box mounting bolts are loose. If the box is loose, it can also damage your chassis :That was during the repairs i had to do to mine, here's a later shot :Not pretty but solid!
