discovery front pinion angle question

rob-o

afternoon all,

ive just been to look at a discovery for sale, and not having owned any landrover of any sort before, (im a lada fan at heart, but i need something bigger....) id like to ask about the front diff pinion angle.

it has about a 4 inch lift, through springs and spacers. it also has cranked front radius arms, but visually the nose of the front diff looks too high, i.e. it is not in line with the driveshaft as i thought it should be. is this normal after a lift? my concern is that the pinion bearings wont be oiled enough, and that the castor angle will be wrong. the seller says that the steering box needs adjusting because the steering is vague, however it has new balljoints throughout and im wondering if it is actually a castor issue. would castor corrected arms solve these issues? (if they are issues)

as i say ive never really looked under a lifted discovery, and im used to the lada IFS setup so its all a bit of an unknown!

anyway, sorry for the ramble, any thoughts are very welcome!

So is the front of the diff pointing down toward the floor (less castor, less weight in the steering wheel) or is it pointing upwards (which would suggest wrong length axle links for the suspension lift fitted) and result in more weight in the steering wheel.

i suppose you'd say the front of the diff is pionting down, i.e. the input flange is pointing up. (and is therefore not in line with the front propshaft)

That's normal and is one of the differences between series and RRC. On average ride height, the UJ's still cancel each other out, and fully up or down the difference isn't big enough to notice.

The whole chassis is a work of genious in many areas, which I guess is why it was built for so long?
Just a shame about the rover 90 diffs Wink
