Lock washer keeps distorting
Hi everyone
The bolts on the lower A-arm shafts are torqued exept for one bolt...
For some reason the lock washer keeps distorting when the bolt is torqued down (by AIM specs).
The bolt isn't damaged at all. Without the washer it torques down OK.
What's the reason for this?
2th washer I tried.

It has to be a poor qualty washer (chinesium maybe?). Try one from a different source.

A typical hardware store lock washer is only gr2 or gr3 at best. You'll need to get some hardened ones from a proper bolt place or sometimes a heavy equipment supply house

I'm sorry to say this but... I've also had this problem when installing my brake calipers. I've bought new bolts and washers from Corvette Central (via their Ebay) about two years ago.
Al the washers did the same thing. So I used P-washers instead.
Does this mean the bolts and washers from Corvette Vendors are al crap?

I agree with above comments on junk lock washers.......I have been cleaning up old originals to use for this reason, OR buy Grade 8....and hope they work.

I've seen a ton of really poor quality lock washers. Working for Harley Davidson as I do I can get quality lock washers and hardware through the motor company. But it doesn't come cheap.
