[TR] IRS rear shock question

[Dave Connitt]

Hi all,
For the second time in 2 consecutive driving seasons, the passenger side (R/R) lever arm rear shock absorber mounting bolts have backed off to the point that the shock bangs against the frame. When noise started the second time I thought it was coming from a loose exhaust but it turned out to be the lower mounting bolt again on that right rear shock. The first time it happened, I applied blue Loctite to the bolt threads but the bolts backed out anyway.
After the first issue I had the shocks rebuilt and the mounting holes on this second set of shocks seemed OK ( not worn out if round).
Has anyone else run into this and if you have, how did you fix it?
Thanks,
