Warning - Broken control arm bolt! - Toyota Yaris Forums

CoryM · 12-28-2012, 10:16 PM

I had a look at the TSB at work today.

They will replace (with updated parts):
Subframe
Ctrl arms
Bolts

As well as they apply seam sealer which appears to try preventing water from filling up the panel that the ctrl arm bolt goes into. I guess they figure that's where the water gets in from. Job pays 5.5hrs WARRANTY time (regular time will be higher).

For most people the best idea will be to remove/inspect, and replace those bolts as required. Salty areas may want to do a yearly check. Next time I have my car on the lift I will see if there is an easy way to make the water drain out by itself. Might just take a drilled hole, or a little cut with a grinder. I completely covered my bolts with axle grease so they shouldn't rust again, but I guess I should actually fix the problem and not just the symptom.

Cheers.
Cory
