I have a 1998 blazer 4 door and i am in process of replacing the power brake booster. after a herculean effort i got 3 of the 4 nuts off the mounting studs under the dash. the last one is behind the steering column mounting bracket. is there an easy way to get this bolt off? is there a special kind of wrench that would work in this tight spot? any hints, i could sure use one.

 

the first one i did I uesd a wrench...PITA....the second one I did I used a wobble extension with a universal joint type adapter and a swivel head ratchet....basically formed 2 90 degree angles with the ratchet and extensions..was still a pain but definatly easier the second time.....getting it started when putting it back on was even worse...I almost left it off...

 

I've used an extension to a universal joint, then another extension and a flex socket. I've put a little putty into the socket so that the nut sticks in to put them back on.

 

thanks guys. i finally got it done. the first u-joint broke to bits as soon as i turned it, but finally was able to get the nut off

 

Glad you got it!! Break boosters are a pain, I did my buddy's on his fullsize chevy and it was no picnic either!!!
