110 Defender PAS type

Long time browser, first time poster and fairly new to the greasy bits of Land Rovers.

My 1990 110 Defender 200TDi has failed it's MOT on a leaking power steering unit as well as a offside draglink ball joint with excessive play, amongst other little bits.

I'll be purchasing a reconditioned power steering unit and get my local mechanic to fit it along with the drag link and a few other bits but I need to check which power steering unit I need.

I believe it to be the 4 bolt type as it has 4 bolts fixing it to the chassis, am I correct in this, or does the 3 bolt, 4 bolt, 6 bolt refer to something completely different.

It's the number of bolts on the top of the steerin' box that tells ye if it's a 3. 4. or 6 type. The one in here is a 6.....

the drag link isn't really that hard to do either....

Many thanks for that Buster, do you have one of those photo things for replacing the track rod and track rod ends as one of the track rod ends has excessive play as well so I've ordered a new track rod tube and two ends (1 x RH thread & 1 x LH thread)

I'll leave the steering box to the mechanics as they have all the axles stands etc but I might have a go at the track rod if it's something I can do with basic tools.

It's okay Buster, don't worry about it I've just found the one you did as well as your other bits and pieces.

Many thanks for all your help
