Haynes Repair Manual never mentioned anything about servicing the steering rack & pinion. Most workshops also refuse to do repairs since it is time consuming and complicated. They always suggest a whole new set (USD1200) or those used ones from the chop shop (scrap yard). That also costs you around USD200. As mentioned earlier, it takes as little as USD40 to get a new repair kit, why waste a grand? You can buy a new set of shocks with that kind of money, man. Just a precaution, the steering gear housing is made from alloy and it is a very soft metal. Do not attempt to remove seals using sharp equipment and never apply excessive force to remove any parts.
The S/V70 has a plastic bearing that in time can cause a squeaking noise when turning the steering wheel. The bearing is located at the bottom of the steering column where the steering shaft goes through the firewall. There is a black rubber boot covering the steering shaft as it goes through the fire wall. The below picture shows the location of the boot. It's a bit easier to work in this area if you take down the kick panel on the drivers side.
This is the left front, with the tire off showing the steering stops that often creek when turning full right or left, if not greased. A thick axle grease will work just fine. Quaker state sells a pint size tin. Apply grease on both surfaces. The steering stops can be reached with the car on the ground and the wheels on.
