Sway Bar Bushing 10mm bolt stuck
 

I am in the middle of replacing my sway bar bushings. My passenger side was relatively easy. However, the drivers side 10mm bolt does not want to budge.
There is not enough space to get a 15mm wrench on the top nut. I tried a breaker bar and it started to round out the bolt, so I stopped.

Any advice appreciated

The book says to loosen the big bolts the go through the LCAs then drop the frame down an inch or 2.

Here is one of the threads on the subject with a few ideas. Basically being inventive.

I soaked mine with PB blaster a couple of shots a day for a week and they came loose easily.
That was 6 years ago, I hope I won't have to replace anytime soon!

I was able to get the nut and bolt free.
I found a 15mm box end wrench that was just small enough to fit over the nut and get a 1/4 turn on it. That was enough to finish it off with the 10mm socket without rounding out the nut.

so sway bar bushings and end links have all been replaced!

Thanks for the replys!

Awesome! Way to stick with it! Guess you didn't have much choice, though huh?

It's a dirty job but somebody had to do it! Now go for a drive and enjoy the ride!
Did you install 90 degree zerks pointed towards the struts for easy greasing?

replaced with stock chevy sway bar bushings..??

Mine are Energy Suspension 25 mm polyurethane greasable , but OEM GM bushings are fine
