On my 1991 mb 350sd I can tell the guide rod mount is loose. So I’m going to replace it, the bushings, and the lower control arm bushing.
Everything went well until the captive nut on one of the main bushings broke. There is very little corrosion but apparently enough on this bolt to cause an issue.
This is what happened:
This is what it should look like, this was the second bolt, same mount, not three inches away.
The access on either side is not sufficient to get a wrench in there. The larger hole is on the inside, blocked by an idler arm, steering shock, transmission bellhousing, etc.
The access from the outside is this:
It’s about enough space to fit a 5/8” spade bit into. Maybe a bit more.
What is my best bet? I’m thinking to drill into the nut, then beat a punch into it and use that to hood the nut. But the punch will be tiny and I’m not sure if it will just bend.
I was also thinking long skinny end of an air hammer, but I don’t know if I’ll have the length or access.
Any recommendations?
Thanks!!
