Pitman nut size 1998 suburban

What size is the pitman arm nut to steering box in a 1998 suburban? Some one said 34 MM. Don't want to buy the wrong size of socket. Thanks Dave

I used a 1 1/4 inch.

Thanks, I think I have one in that size. Dave

I seem to remember them being 1 5/16".

Thanks, I think I have one in that size. Dave

34 MM would be around 1-/5/16 to 1-3/8 .

Thanks!
I did stick a wrench on mine first to be sure. It's probably a 32mm really.
I'm still using the stock nut. I didn't get a replacement last time I changed that arm, but I have received replacement nuts on front end parts of different O.D.'s.
Most of the time I replaced with Moog.
