1988 Ninety Disco Engine and Power Steering....

....what's worse.....removing the drop arm from the PS Box or removing the drop arm ball joint??

Couple of things to do for the MOT, Ball Joints on the Drag and Track...and the exhaust....

They are both crap jobs
I recommend you take the box off, take it to a local tractor shop and get them to pull the arm off.

Thank you can upgrade to discovery style steering with a normal screw in ball joint.

You will need a discovery steering drop arm, a discovery steering rod and a bracket to bolt the steering damper to the discovery arm.

I have done this upgrade to two separate vehicles and would recommend it to anyone.

Drop arms can be difficult to remove, although they do come off with a decent puller and hammering.
Changing the ball joint in situ is pretty easy, takes about an hour.

Grand....

Many thanks for the advice, I will have a go at changing the drop arm ball joint first....then sit and lick my wounds and get the hydraulic puller from work to pull the arm off if the ball joint doesn't budge.....

As this is a long term project for me (well it is the girlfriends car as she has wanted one for fecking ages) I will look into the Disco mod, as it will be easier for future maintenance, just got to get the thing through the MOT first!!

Use a small bottle jack and a little piece of broom handle or similar. Jack it slightly under the joint, to lift the baseplate. Remove circlip with pliers, and the works will come out, all except top race. Put a wood block under the arm, and beat out top race with a hammer and drift.
Make a little puller with a bolt and a steel plate to pull in the new top race. Then rebuild the rest as it came out.
I would get a genuine/OEM kit. the cheapies sometimes don't work.

Beat the top race downwards, or upwards?

Here is the kit you need.

Sumo drag bar 830mm
Lemforder LH track rod end
Lemforder RH track rod end
GL79 RHD damper mount
Discovery drop arm

ignore the bit about it only fitting 3/4 bolt power steering boxes as it fitted my 6 bolt no problem.

If that's a bit expensive for you than just fit a standard discovery steering rod rather than the heavy duty sumo bar
