Guest leapingcat1 Posted March 24, 2005 Share Posted March 24, 2005 new to supras so bear with me-recently purchased mkiv non turbo supra went to toyota twice to find cause of knocking noise from suspension/anti roll? they can report nothing! its annoying and is felt over rough ground/roads realise it could be anything but does anyone have any common known causes also original 16" wheels fitted and the camber seems to cause excessive wear on the inside of the tread pattern-any clues? cheers Link to comment Share on other sites More sharing options...
toyotasuprauk Posted March 24, 2005 Share Posted March 24, 2005 Dont know really but it was anti roll bar bushes on my celica that solved the problem. Not surprised Toyota couldnt find anything though. Link to comment Share on other sites More sharing options...

Causes could be Sub frame bolts Shock beginning to go but still dry. Incorrect tightening of suspension components ie without any load on the system.

jaymdee Posted March 25, 2005 Share Posted March 25, 2005 Something else it could be is the top coils of the suspension springs knocking together when travelling over rough ground, particularly at slow speeds. I get this (Eibach pro-kit) and found that with 2 people in the back, the noise goes as their weight is enough to keep the coils touching - when it's just me they move apart slightly over harsh bumps and come together with a bang/knock. I've also tried putting something around the coils, but not with too much success. Have a look to see whether your top 3 or so coils are touching. If anyone can suggest how to cure this permanantly, please let me know cheers J Link to comment Share on other sites More sharing options...
