Steering box overhaul


Gidday All,
Would anyone know or can recommend someone in Brisbane that reconditions/overhauls steering boxes?? I have a '73 Bay window with about 4" of free play in the steering and the screw on the box has been tightened to the max. Any help would be much appreciated.
Thanks.

any help
get another one
try brad from COR

Where would Brad from COR be located 13bwagon???
Thanks for your reply Lee..........But the bus s/boxes do differ from the beetles

don't know if any help but my old bus you had to book a turn so i was told to fill the box up with heavy grade grease and dam it worked very good still was working well 4 years later i was told that most of the oil leaks out
happy bussing

Sounds good at this stage greedy53.......Mick from Mick Motors can arrange a recon job on it for around $245. The price to me sounds great, but I don't have the confidence to pull it out myself and replace it.
Thanks for all your help so far everyone too........It is appreciated, I kid you not!!
