 |
|
| I am attempting to replace the shocks in the rear of my '69 SQB. It appears the bolt for the top of the shock threads into a spinning captured nut inside the upper portion of the subframe. Is there a trick to this, or am I cutting the frame open to access and welding it shut again post R&R? |

| I'll report back. I had hoped there was some secret with respect to the bump-stop pad being removable, but it appears not to be. |

Turns out VW spot welded a simple "wrench" over the internal nut in the upper rear shock tower. I guess they didn't have wire or rod welding capability on their assembly line, only spot welding which would explain this poor approach to a captured nut. Once rusted the bolt spins the nut and the "wrench". Another scenario (likely mine) the bolt rusts onto the bush inside the upper shock. When you spin the bolt it can't move outwards, so the internal nut moves inwards forcing itself out from the "wrench"
For the love of Mike people, please replace your shocks if they look at all rusty. These look to be original and well composted. |

Looks like you fixed it. I do agree with you on the shocks needing to replaced every so often thing, especially if you live in the "salt belt" or near the ocean.
