Guys,
allow me to ride on this thread as i am having this problem with my blm.
Recently i hear 'kluk2' sound on my blm. It happen during initial movement when load is transferred to the back. Its very faint that the radio needs to be switched off before the sound can be heard. Its like a metal to metal sound. A quick inspection reveal that the 2 bottom engine mounting is torn thus i replaced all for last sunday.
Car felt like new but the noise is still there and can hear more clearly as the new mounting seems to lower noise coming from the engine. Lower arm is new (less than 1 yr and its ori Proton), no significant free play on tie rod and absorber link to arb. I am starting to think its the caliper pin. How do i check the pin?
