I'am familiar with the whole procedure for changing the bushings. The bushing were replaced twice in the period of 3 weeks, they were just shredded.The first one was done correctly but the bushings gave up in just 2 weeks of driving on Islamabad roads. The second install done was just useless by the mechanic because I wasn't there watching him due to some work related emergency. That man didn't know how to fit the bushings, and thus by hammering one of the link joints, he bend it by about 2-3 degrees, due to which the whole rear suspension is bend to the left tyre. Now that has led to all the rubber parts in the whole suspension to fail and the vibration in the cabin now is too much than it used to be.
