    Angle gear.

    Does anyone know if the angle gear is the same in a S60R, and a XC90 2.5T, both manual? My thinking is, if they're the same, I might buy a spare, and recondition it, just in case.

    I believe it is the same as the XC90 (collar gears are the same so cant image the angle gear being different).

    Best thing to do is get underneath and have a look. Some angle gears had a chain drive unit attached, there are that many different versions. They did a strengthened version too.

    also it will require the same drive ratio as the rear axle, if you are building it as a swap in unit should anything go wrong with the existing unit iirc

    Are they not all 1:1 ratio?

    yes in theory when with the matching rear axle. so if for example the rear axle is 3.31:1 then the angle gear needs to match it but in reverse so 1 input turn gives 3.31 output to rear diff, thus in reality at the angle gear input 1 turn will give turn a the rear axle so a theoretical 1:1 overall. If I'm wrong in this thinking please shoot me now, but that is how I understand it, Dangerous Dave will be along in a minute if I'm wrong with a proper explaination

    I thought they were 1:1 and box matched the rear diff.

    Can check in the morning now.

    My understanding is, the front and rear diff are matched, and the angle gear is 1:1, just to turn the transverse output from the gearbox, to the longitudinal drive to the propshaft.

    Nope, fraid not.

    Early ones were 3.31:1 to match the final drive ratio of the diff (which was inherited/modded from the 900 series). If you check my build thread (in my sig) I've got my angle gear dismantled and you can see the difference in the gears.

    Think the later ones were changed to 2.78:1 (I'll have to dig out the data to check that and what year they changed)

    The front diff works seperately to the rear diff, think of it as the angle gear is added (bodged on LOL) to the drivetrain after the front diff, so you need an overall 1:1 ratio through the angle gear and rear diff.

    Bloody mind flock

    If your having a spare, just buy a good one and weld the sleeve.

    Mines very low miles 38k from a p2 2003 but shaft is worn even at low miles, but otherwise perfect, I'll weld a new sleeve on and keep it as a spare, not that it fits my v70r

    That one is a later model with different/stronger bracing cast into the casing compared to the early ones

    This is what happened to Husseins (lookforjoe from VS) looks like an earlier model of angle gear

    Was thinking about doing this to mine but the problem is that it might wear the gearbox splines more which is about the same amount of cost to replace

    Had about 500 odd bhp didn't? Not surprised it did go, I know they break if launched lots but I'm guessing his power upgrades didn't help.

    Looking at his videos at that time I think it had a 19t and was running about 280whp. It was launched hard by the looks of it It's completely different now, he's modded it loads

    Our S60R has been launched hard many times, I think the failures people have suffered are because, they don't realise they weep oil, and they run them dry, as they don't keep them topped up.
