hi just got service oils for my 97 300 tdi disco and looking at the axle gear oil it say's ep90 apl gl5 spec though haynes calls for ep80/90 apl gl4 is the gl5 spec ok to use thank's in advance not changed oils yet

just a refresher can i use GL4 EP80/90 oil in my diff's local garage near me selling coma £4 litre thank's in advance

hi have you checked your power steering fluid level also look underneath on the o/s at the steering box is it leaking from the drop arm seal this happened to me had to replace steering box.

ref 300/200 tdi engine quickest way to tell the difference look at oil dip stick tubes 300tdi at front of engine 200tdi on the right hand side of engine as you look into engine bay

ref power steering box did this job last year on my disco took me roughly 4hrs with disco on axle stands easy enough to do just awkward because of the size and weight of the steering box mainly 17/19mm spanners steering box bolts. 13mm steering linkage bolt under bonnet also 16mm spanner for one of the top fluid hoses just take your time. but i done what disco-ron said brought new box complete with drop arm fitted (pig of a job to get off ) when ordering just look at the drop arm on your box it will be straight or bent. I brought mine from craddocks £250 exchange also dont forget new power steering fluid with disco on level ground and to bleed system afterwards by undoing the bleed nipple on top of the box fill resivior start engine turn the wheels left to right lock few times check level tighten nipple clean up check for leaks hope this as been helpfull
