Changed the pass side today. Tried that wheel well removal, but didn’t have any luck getting it off.
So I tried the skirt only approach. Seems to give you some room, but not much. Anyway, don’t give
up if your just changing that back two on the pass side. They are knuckle busters though. A little
PB penetrating lube helped get them off along with that universal and a long extension for that center one.
That back one was hard, so I did it first. Used a stubby there along with that universal. I also put the rig
on jack stands one on the cross-member and one under that rocker arm coupling just for s & g.
The one on the cross-member was holding the box up okay. Those push pins are though, but not impossible to get off. Just keep at them. The first plug toward the front pass side, I had to remove the
water/coolant tank out of the way, that gave me plenty of room from the top. Not sure if it would have
been just as easy from the bottom as it was already done. Good luck, and DON’T QUIT!
