jts99OBW Posted December 14, 2005 Share Posted December 14, 2005 Yep, I'm new here. I started looking here to see what was the trouble with my '99 OBW. It appeared a classic case of torque bind, but I have a MT. So it turns out I have a bad viscous coupling (VC). Nothing that $1100 won't fix. My question is that at about 80K miles, this seems a bit premature. I know the issues of tire size and rotation and I'll check to see if that was the cause. Any other issues that can lead to VC failure? I don't want to leave the cause unrepaired and look forward to shelling out another chunk in a few months.

wrxsubaru Posted December 14, 2005 Share Posted December 14, 2005 I would hust stay up on tire rotation, air preasure, and keep thje tires matched. Abusing the center diff making it work hard(having a tire in the air) will cause it to heat up and that will take life away, but thats about it. Ive been very abusive and have never had a problem with them so maybe it was complete neglect, or maybe a defective center diff. Quote Link to comment Share on other sites More sharing options...
jts99OBW Posted December 14, 2005 Author Share Posted December 14, 2005 I don't think I've abused the system. I have four Michelins of the same vintage. I've kept up rotation reasonably well. Once I lost some pressure in one of the rear tires and heard a strange rumbling on deceleration. When I corrected the tire pressure, the rumbling went away. An interesting note: I was looking at a 2005 Outback XT at the dealer lot. It had about 18K on the odometer. The front tires were almost to the wear bars, the back ones looked like they were new. Must of never been rotated. I brought up the issue to the salesman. His reply: We'll put on two new tires if you buy today. Quote Link to comment Share on other sites More sharing options...

WoodsWagon Posted December 15, 2005 Share Posted December 15, 2005 Personally, I'd just make sure all my tires were the same size and drive it till it becomes unbearable. Then just put in a junk yard tranny for 300 bucks. Quote Link to comment Share on other sites More sharing options...

vic/se Posted December 15, 2005 Share Posted December 15, 2005 Anyone done handbrake turns in that car? you rise a good point!!! Quote Link to comment Share on other sites More sharing options...
jts99OBW Posted December 15, 2005 Author Share Posted December 15, 2005 Yep, I'm the original owner. I got over 50K on the OEM set of Michelins. Replaced them with the same product (XW4, I think). As far as handbrake turns, I can barely get the e-brake to hold on my driveway, so I would be surprised it it could lock the wheels at speed. I notice some folks run their tires at higher pressures. Could that put less stress on the center diff? Quote Link to comment Share on other sites More sharing options...
nipper Posted December 15, 2005 Share Posted December 15, 2005 as long as all tires are the same PSI, and per subaru spec within 1/4 inch of circumfrance (sp) you should be ok .. normally. Sometimes stuff happens nipper Quote Link to comment Share on other sites More sharing options...
Strakes Posted December 15, 2005 Share Posted December 15, 2005 Has the car ever been towed by a yahoo that left two wheels on the ground? Quote Link to comment Share on other sites More sharing options...
LosDiosDeVerde86 Posted December 15, 2005 Share Posted December 15, 2005 and you reply to him "it's a subaru, it needs 4 new tires, not 2" yeah, i'd be hard pressed to buy a car with tires like that. tires like that means the previous owner didn't take care of it and lord knows what else didn't get taken care of. generally you want to stay away from a tire different of 4/32 or more.

sparklemotion Posted December 15, 2005 Share Posted December 15, 2005 How does that screw up a VC? I've had to replace one in my 99ob but didn't know why. I'm sure I've done a few handbrake maneuvers over the years. it's so hard to force myself not to do that in the snow....it calls to me.
