[Healeys] Nord Lok washers

I think the problem is that the bolts
might loosen a little and then the shock starts
moving a little and then the bolt gets tightened even more.
If it were the casting's fault, so to
speak, then why don't the later rear shocks with
the larger bodies and every MGB MGA TR6, etc
which use the same large body ever show the same
kind of wear? (large shocks defined as 4" on c... small shocks are 3-5/8 on
In the case of small shocks, those used
on Spridgets do not have the problem. Those used
on TR3s and 4s DO have the problem of loosening.
Front shocks.... Healeys often have
oversize holes, as do MGAs, though less so. MGBs.... never (same castings)
Your suggestion would still need a good
lock washer, and these Nordlok things look just the ticket.
By the way, Armstrong's first castings
on say an MGTD rear shocks had steel sleeves in
the holes. A possible solution we're looked into.
Also, it is difficult to tighten the
rear shock bolts with a "normal" socket as they
are often just a little too thick walled, in my experience.
Again, I'm looking at thousands of
shocks that share the same castings, yet only a
select few cars seem to have the issue.
