blkaplan Posted August 23, 2006 Report Share Posted August 23, 2006 I have heard that the angle gear on the first gen. awd cars is weak? Who here has blown one up? Under what conditions did this happen? What type of power?Thanks Link to comment Share on other sites More sharing options...
fastboy Posted August 23, 2006 Report Share Posted August 23, 2006 I drive like a dick and haven't busted mine yet. But they do go. Eventually.edit: there is a sleave which can get stripped and grind like an SOB that can be replaced. On most 98's with awd problems after it's replaced all is well again with the angle gear.

blkaplan Posted August 23, 2006 Author Report Share Posted August 23, 2006 Do they go due to neglect or are they truely weak? Link to comment Share on other sites More sharing options...
fastboy Posted August 23, 2006 Report Share Posted August 23, 2006 mine's a stick and has taken one hell of a beating everyday for the past 60,000km... they just go when they want. I haven't seen one just grenade. I don't neglect my car at all, but we have 98 XC's come in with 300k + on them with no service and we have no issues with them. I have seen a lot more fall on 02 and up P2 cars. Link to comment Share on other sites More sharing options...
Johann Posted August 23, 2006 Report Share Posted August 23, 2006 Do they go due to neglect or are they truely weak?Weak because they are part of a very weird driveline. The visco mid diff activates when the front and rear wheels have different speeds. When the front tires wear to much compared to the rear tires the visco is engaged slightly and will put a load on the angle gear under normal operation, lets say highway cruising. Because of this there will be a lot of heat in the angle gear and as far as I know this wasn't intended. The angle gears will start to leak and eventually run dry. With the newer models the angle gear isn't that much different but thye visco has been replaced with an electronically controleld visco which only activates when wheelspin under certain circumstances is detected. There isn't any load under normal driving. Neverteless the newer angle gears show the same leaking problems. Many angle gears on new R models have been replaced either under warranty or customer paid. In some cases twice on the same car.The other weak part is a spline ring between the angle gear and the gearbox btw.Maybe with some cooling and a solution for the leaking problem, mostly through the vent nipple, I think they will hold some longer.With the spline ring it is important that it is absolutely free of play when mounted else it will eat itself away and the metal shavings will cause the input shaft of the angle gear and the output shaft of the gearbox to be destroyed in the process.

garbergtsi Posted August 23, 2006 Report Share Posted August 23, 2006 there all pretty weak, ive seen them go bad on 98's up to 04's. Link to comment Share on other sites More sharing options...
firepuma Posted August 23, 2006 Report Share Posted August 23, 2006 Boom! Mine went at 140,000K after 20K on a lowered, bigger wheels setup Link to comment Share on other sites More sharing options...

Or are they a sealed unit? Link to comment Share on other sites More sharing options...
gdizzle Posted August 24, 2006 Report Share Posted August 24, 2006 Thanks for the informed answer, it is refreshing.Are angle gear drivers flushable? Or are they a sealed unit?flushable, you have to pump all the fluid out then refill, obviously. Link to comment Share on other sites More sharing options...
Big Will Posted August 24, 2006 Report Share Posted August 24, 2006 Greg, I know the fluid in my angle gear has been topped up a few times and so far so good but does it get flushed under normal maintanance at any point in the service intervals? I've never seen mention of it. Link to comment Share on other sites More sharing options...

I've never seen mention of it.i don't think so. There was a bullentin out for the fill level IIRC and maybe even a change to the fluid type. There is a DIY write up on v70r.com on how to change it. The reason volvo changed the fill level was because the oil was expanding to the point that it would completely fill the housing up and cause the seals to leak.

Boosted5cyl Posted August 24, 2006 Report Share Posted August 24, 2006 in addition to above info what HP you guys pushing on um, seeing I'M like the one guy with an R w/o exhaust, chip, etc, still ! Link to comment Share on other sites More sharing options...

At least I'm confident that the level is correct at the moment and I'm careful about rotating the tires.As for HP, if IPD is to be believed I'm somewhere in the 230 hp vacinity. Greg's old R probably had a fair amount more than that. Link to comment Share on other sites More sharing options...
Boosted5cyl Posted August 24, 2006 Report Share Posted August 24, 2006 no I know dizzle was higher than that cause stock HP's 236 If I recall Correctly. All in all I guess it's nothing to be concerned about till your quit modded. Good enough for me, but I am going to V70R.com for the write up on the fluid change !
