While the hub is at the machine shop getting a thread insert, I started pulling out the busted knuckle assembly from the truck. The nuts holding bearings weren't willing to budge so I had to use my impact gun on them. The spindle threads are definitely kaput.
Once the nuts came off the claw...
@PADDO is generally considered our resident expert on AHC - tagging him/her in hopes that he/she will chime in.
I had to pull AHC from my truck because I had only 6 gradations difference. It can be reliable if it has been maintained and if the rust doesn't kill the shocks or hydraulic lines.
8 marks between low and high is disappointing. If you end up with the truck you can flush the AHC fluid and see if it gets any better but I seriously doubt it. Conversion to LC can be done for about $1000 if you are willing to get your hands dirty otherwise it will be about $2k job.
That seems to be the going rate for clean, well-maintained example. Check for rust (I imagine a non-issue is an AZ truck). I would still set aside another $2k for suspension work and other eventualities that are part of 20 year old truck ownership reality.
Thanks @suprarx7nut and everyone else who helped put this to bed. You guys spent you time, money and skill to help move the knowledge marker forward and debunk some hearsay.
WATCH THE VIDEO - WATCH THE VIDEO - IT IS WORTH IT!!
For anyone who doesn't have time to watch 13 min video right away...
Cleaned up the hub and got all surfaces prepped for installation. Started putting on the new rotor and stripped one of the bolts :bang:
Tried a theeading tool to rethread the hole but unfortunately it is too large. What are my options here? A helicoil insert or can I used a grade 10 through...
