Defective Idler Arms
Sorry to say all replacement parts suck now a days.
Replaced 25 year old axles in a Toyota Camry. 3 years later the boots are blown out. My 318 truck fuel pump was replaced 5 years/20K miles ago. Started leaking like crazy.Damn near set the thing on fire.
Rebuilt the front end with parts from Year One. 3 years later all the boots rotted away.
Nothing is made to last anymore...
One more . Ordered a front end kit from Jegs. Got a notice that the ball joints were recalled. The wanted me to send them back on my dime and pay shipping for the replacements. I just thru them in the scrap. Was cheaper to buy new. Junk parts .
