As per my strip and build thread, I am having a problem with the steering coupling and getting it undone.
Can anybody give me some guidance as to a trick or best practice to get the coupling unbolted.

You can call me thick if you wish, but I must be missing something to be able to a spanner onto the coupling, with the body on (I might add)

I've never had a problem. Are you using the correct size spanners? Nut is 13mm spanner but the bolts are often 14mm.

access wise just turn the steering a 1/4 turn at a time and do the one that is accessible or do a 180 and remove the opposites otherwise take the clamp bolt out of the box end and pull the column up off the box to get better access.

Thanks guys, I will have a play tomorrow morning.

The fight continues as will my unbuild rebuild thread..... 

its off..... with some grunting and wiggling whilst the body was slightly elevated....
Phew that was an epic.

Thanks for advise
