John,
I am not sure which steering gear was used on the 96 Monterey, and since you did not give your location, it is difficult to recommend a shop for the repair. You will also find it difficult to find a shop that will reseal your steering gear because most shops will only exchange it with a rebuilt gear, even though the average steering gear will only require the replacement of one seal to repair a leak. The need for specialized tools and training makes the seldom see steering gear repair impractical for most shops.
