Few XR8 Q's

[MGM]

hey guys, i recently bought an au3 xr8 ute, which is sort of an upgrade, but not really. Just for work

ive got a few small problems with it but other than that its a good car.

Problems:
1. The steering wheel feels like driving a BA, as in the heavyness of turning, whereas my AU3 XR6 ute the steering is super light compared to this. is it normal for the XR8 to have heavier steering?

2. My brakes wernt working as good as i could remember my XR6 ones were before i changed to BA ones, so i took all the XR8 brakes off and got the discs machined, new pads all round and new fluid. I found that 2 guide pins in 2 callipers were siezed so it got them out and regreased them up and its made a huge difference. But i still have the problem that when im pulling up, almost stopped, the brake pedal pulses when the wheel is turned as if i was stopping on mud and the abs has kicked in, then the abs light comes on and only goes off if i turn the car off then on. I cleaned all abs sensors and no fix.

Could this be because of the wheel bearings need replacing as they are a bit noisy, but no play in them.? only happens when the wheel is turned i think.

3. ive searched around but didnt find the answer i was after.

Ive got a ticking sound when the car is on and its warm, coming from the passenger side underneath, ive popped the bonnet and its not the carbon canister in the engine bay. Almost sounds like where the abs unit sits, i think its the unit for that.

4. When going from no throttle to light throttle the car feels like its in the wrong gear for about 1-2 seconds and doesnt have responce, then kicks back and goes as normal, is that normal for an auto, as ive been driving a manual xr6 and more use to direct power, and being in the right gear.

Thanks in advance for any replys
