I have a problem.. Having buddyclubs n+ coilovers

the locking perch of the front left coilover loves to come loose!

Anyone have a problem with that? common or rare?

and when i reverse out of a hill up slope hill, i hear a clunk.. and it destroyed my wheel alignment and i just got a alignment 4 days ago lol .going straight line my steering wheel is bout 2 cms to the right, BUT it veers to the left when i try to straighten the steering wheel.

Just wondering will this destroy my tread on my tyres due to the steering wheel out of place and will this also affect my toe out?
