hi 2353,
i have never experienced this.
a couple of questions –
Does it happen every time you put the steering on full lock or was that a one off event?
Does it happen on both left and right lock?
Assuming it does it repeatedly…
it could be any of the ball joints or the rack. It won’t be in the steering column itself or it would happen before you got to full lock.
If there’s nothing obvious stuck on track rods or the ball joints – like a twig or a stone, then it would have to be the rack or the top or bottom ball joints.
To find out which you would have to separate things – the easiest and most effective step would be to separate the track rod ends from the hubs and see which one sticks where.
If it is something sticking, then it may free up with a good squirt of grease from a decent grease gun – if it’s a top or bottom ball joint that is. But it could be a good idea to take them apart to clean and grease them – for which you’ll need the tools. If it is the rack, then it will need stripping I think.
Sorry not to be more specific.
Let us know the outcome. Thanks
Chris
