You can also tip the diff back down , may be lots of work compared to ordering a new shaft. I’ve been running mine like this for 20 years. No vibes both angles equal No idea on the slope never checked it.

I also added Pertronix electronic ignition and it starts instantly.

I'm looking into this too. Do you have the Part numbers you used?

Howdy All,
I wanted to report that I have been daily driving the rig and I would highly recommend Tom woods to anyone who is struggling with any driveline issues. I have been side tracked by another project but now I have more time to tinker again. I wanted to post my front Shackles and see if anyone has information about them and if they looked to be installed correctly. I find it odd that the bumper is being used as a stop.

I remember those shackles. Kind of a late 90s fad to get extra flex. I believe they are in the correct configuration. Never tried them myself though, always assumed they would be noisy and unpredictable off road. Yours seem to have survived well though.

Thanks for the info, it handles well enough and the SOA has grown on me so just going through making sure I don't need to prioritize anything.

Shackles are not install correctly , it not suppose to contact the bumper , they should be turn 180° .
Better is to get stock shackle, and remove the two short leaf

It definitely didn't seem right to me. I may try to flip them but if I decided to go to stock shackles are you saying I would need to get a new set of springs or just drop the short leaf?
I worry that it is gonna mess up the stance because right now I like how it looks and rides.

Those shackles are inverted and that thing must ride terrible.

This is on the rear, but orientation of shackles would be the same if they are installed in the front or the rear.

I agree, there is no shackle movement or swing in its current orientation. Yrs ago I wheeled with a couple of jeeps that had those shackles. I watched one of them roll on its side, because he couldn't feel how light the right rear was because the wheel didn't lift. On the other jeep I had more suspension flex in my 40 with a conventional 4" skyjacker lift in certain situations than the terraflex shackles did.

Looking at the relationship between your spring eye and frame mount, you should have a great shackle angle with a standard style shackle at the appropriate length. I usually make mine out of 2" flat stock that's 3/8" thick.
