Default Have I got 2 seperate issues or are they related?

Issues

1. Shudder on braking, doesn't feel like warped brake discs, but feels more driveline related. Could be the discs though.

2. On full lock I get crack/knock from the suspension, especially when reversing out of my drive then hooking a sharp left, big knock comes. Happens when going forward, only at slow speeds though, around 10-15mph.

3. Running Contis on the front, car doesn't feel as planted as it should be, a bit wandery, it has been hunter aligned which showed nothing odd.

Tyre pressures are 33psi.

I feel as thought I should be looking at replacing my lower control arm bushes, I'm going to check out the steering rack bushes aswell even though they're only listed for pre facey cars.

Stab bushings, then lower control arm's rear bushings, then steering rack bushings. Should sort you out.

Replaced the anti roll bar bushing and also the rack bushing.

Still knocks and cracks on full locks. Can feel the suspension jerking underneath.

Took a look again today on a ramp and can't spot anything loose.

Will replace the crontrol arm bushes aswell.

on the brakes issue, I was getting the same problem. Turns out, the pin that holds the caliper bolt in place was either not reinstalled during my last brake job or it broke/popped out. My caliper was sliding on the rotor just a tad, but enough to make my brakes shutter/stutter a bit. replaced new pads and put new pin in, and I am good to go again. Not sure if you have the same issue, but it is a possibility.
