Ah. Gotcha. Point of no return then. BFH and a 10-12" bolt or cut some all thread to length.

I know all about burrs. I have ruined a few things over the years. Like a $80,000 coupling for a shaft.

Coupling was a interference fit. Meaning the bore of the coupling was smaller then the diameter of the shaft it was going on. Shaft diameter 12.000". Bore diameter 11.980", 0.020" smaller. Have to heat the coupling up to expand the bore diameter. Heat it 600F to grow the bore to 12.010". Start to slide the coupling over the shaft. Coupling started to cool off. Picked up a burr about 90% of the way on. Stop the coupling dead in it's tracks. Hurried up and threw more heat to the coupling with 3 rose bud torches. Stuck! End up machining off the coupling and ordering a new coupling.

What saved my bacon on that job. I had the foreman right there with me, giving me a hand.

What makes the diff bushing install hard is that it just like the above, but without the heat. And the sub-frame hole is not perfectly round either. It's somewhat egg shaped from the welding on the sub-frame.

I’ve stuck 2 in from the rear

Keep going; while pulling in with the bolt, occasionally smack the bushing side with a 5# hammer

I'm gonna keep chugging at forcing that B in. just picked up an entry level BFH, 32oz. If that doesnt work, I'll rent a 3# sliding hammer from autozone, if that shaft is 1/2", otherwise I'll have to find thor's hammer

Thought that hole was a tad larger? 9/16” or maybe 5/8”

Measure that hole Bunk

You could potentially get a larger threaded rod & nut to work with

Need at least 6" of girth.

13mm is the biggest you can go.

EW always argues anything over 5 1/2 is just too much.
