p4blo32 Posted June 30, 2015 Share Posted June 30, 2015 Hi guys, I had new bushes fitted to both banana arms in February last year, since then the car has done about 12K miles. Had a look under today because a knocking noise has cropped up again and have seen both bushes have failed and the arms are touching the metal above. This seems like a very short life span to me, they were genuine Nissan items and them seemed to be fitted fine at the time. Is there anything that would cause them to wear so quickly? I wonder if both ends of the arms are knackered and maybe that caused excessive wear, in that case I guess I'll have to replace the arms themselves. By the time I've had the bushes replaced, arms put back on and all aligned the total price is starting to hike up anyway Quote Link to comment Share on other sites More sharing options...
Mack Posted June 30, 2015 Share Posted June 30, 2015 I had my compression rod bushes fail and had Super Pro bushes fitted by Horsham Developments. 2 years later they are still tight. Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted July 1, 2015 Share Posted July 1, 2015 It is very unusual for oem bushings to fail so quickly. As the centre of the bushings are off centre they do have to be pressed into the compression rod in a fixed position for caster tollerences. If this has not been done correctly then extra load may be placed on the bushings causing premature failure Also: The maximum force to remove the old bushings must not exceed 4,49 tons. The maximum force to fit the new bushing must not exceed 3,93 tons. And finally a force of 1.12 ton should be applied to the new bushing (once fitted) as a test to confirm that it is tight enough in the compression rod. If any of these 3 tollerences are negative, then new compression rods should be fitted. PM on its way with more info: Alex. 3 Quote Link to comment Share on other sites More sharing options...

"But fortunately for Alex, he can exert a force of 5 tons with his index finger and can gauge the difference from his 1 ton pinky finger" some might say.
