Check belt, check UJ's, check the pipes for signs of oil leaks near the box & pump.
Loosen the top right bolt on the pump, then the two others and using a piece of wood, wedge it in between the pump and outer timing case and give it a nudge to tighten it, alternatively use the 1/2 square hole with a bar to do the same, then tighten the last 2 bolts back up, then the top right one ( all 1/2 or 13mm )
With the UJ's, loosen them up and remove, give em a good inspect and lubricate ( make sure you note which way you removed them, its a pain trying to replace them the wrong way around and mark em
) UJ's are cheap enough so it's worth grabbing some new uns and fitting.
When fitting, make sure the wheels are aligned true and the steering wheel anorl, a good trick is to wedge a piece of wood from the dash and through the steering wheel onto the headrest of the seat, keeps it from moving whilst fitting everything.
Also check the drop arm bolt whilst you're there, make sure the tab is fine and check all linkages, any looseness will require attention, don't forget steering can be a funny fooker, what seems like one problem can be something totally different.
