#17956 of 18377 Re: 07 Impreza no rear end traction? [jiromo] by kurtamaxxxguy Jan 10, 2009 (10:56 am)
Replying to: jiromo (Jan 10, 2009 10:27 am) my "guess" is something has gone wrong with the rear differential. Many earlier Subarus (through around '08) used limited slip rear diffs, and if the diff's clutches have locked up, then it will not properly distribute power to the rear wheels, and cause fishtailing.

#17957 of 18377 Message---Ill 5 by saywhat Jan 10, 2009 (11:42 am)
I've been getting the message Ill 5 on my speedometer on and off.   It comes on for a minute or so then reverts back to the regular ( how many miles I've gone).   This is a 05 Legacy Turbo automatic.   Thanks for your anticipated help   Bob G Replies to this message: samiam_68 (Jan 10, 2009 2:47 pm) saywhat (Jan 10, 2009 11:17 pm)

Replying to: jiromo (Jan 10, 2009 10:27 am) There should be a note in your owners manual about replacing tires. IIRC, replacement tires should have the same or nearly the same tread depth as the other tires. something to do with the AWD. I'm sure that someone with more knowledge will have something to add.   MNSteve

Replying to: kurtamaxxxguy (Jan 10, 2009 10:56 am) My guess is the new tire you had mounted is not the same as the one you have on the other side. In AWD Subarus, all 4 tires should have the same circumference with a 1/4 inch deviation tolerance. The faster the speed, the more the disparity will show and wreac havoc with the AWD system, which, in turn, can cause fishtailing.   Just because the tire may have the same spec size such as 215/60R16, it doesn't mean the circumference will be the same. Have a dealer check this out ASAP before the AWD system gets damaged. Replies to this message: kurtamaxxxguy (Jan 10, 2009 6:34 pm)

Replying to: saywhat (Jan 10, 2009 11:42 am) I think Ill 5 = ILL 5 = ILLUMINATION level 5 = dashboard illumination control. Replies to this message: saywhat (Jan 10, 2009 11:17 pm)

Replying to: jiromo (Jan 10, 2009 10:27 am) "07 Impreza AWD 11,000 miles Automatic... rear passenger tire flat... nail sticking out of the sidewall... had to have the tire replaced locally. I couldn't find the exact match for the factory tires (Bridgestone). So, I had to have a BF Goodrich with the same specs installed... took my car (50 miles) to Subaru... for other service... This morning, I got in my car and on to the interstate. I was going about 70 and the rear end of my car just started coming out from behind me. It was like I was driving on ice. There is no ice. It's too warm for ice. The roads were a little damp... The rear end of my car just start skipping/jumping and shuddering...."   Page 11-36 of my 2008 Forester Owners Manual says: "Mixing tires of different types, sizes or degrees of wear can result in damage to vehicle’s power train."   It sounds like the new tire could be mismatched enough to damage the AWD after the fast 100-mile trip to the dealer. Perhaps the new tread increased the diameter too much, or perhaps the new tire is even a size larger (check it). In those cases, I would think the Tire Pressure Monitoring System would detect a mismatch in diameter -- which is how it monitors pressure. If your car has TPMS and the new tire was a problem, a warning light should have showed. Replies to this message: cptplt (Jan 11, 2009 3:48 pm)

Replying to: samiam_68 (Jan 10, 2009 2:45 pm) The '09 Forester manuals warn of the same condition wrt mismatched tires.    There should be mention in the Drivers manual of a fuse you can install to disable the AWD system (in the Forester, I believe that fuse is inside the car on the fuse panel near the driver's left knee). Once that fuxe is inserted (you can get spare fuses in the fuse compartment under the hood), the vehicle reverts to FWD only and an AWD symbol, indicating AWD shutoff, should appear in the instrument console. If your shudder / fishtailing goes away when in FWD mode, that would suggest the problem is with AWD imbalance or possibly the rear differential.

these days anyone w/ internet access should be able to match tires easily... if you have a spare (even a donut), go to someplace like Tire Rack (tirerack.com) and have them ship you a replacement (assuming they can still get it); even if they can't get it they can tell you what tires match the diameter of your current ones.   I almost always buy from tire rack and have them drop ship to my local installer.
#17965 of 18377 97 Postal Legacy no AWD by albrase Jan 11, 2009 (9:15 am)
Hi. New to this forum, but have been a motorhead for 50 years. I'm trying to fix a 97 Postal Legacy that gets no drive to the rear wheels. My wife used to be a rural mail carrier and bought this rather hammered Legacy from a guy on Ebay for $5000. Winter came and the car would get stuck in its own shadow. I got to know the local dealer service manager and they ran some codes and decided it was either the transfer clutch solenoid or perhaps one of the VSS's. I ripped the rear housing off the tranny and replaced the solenoid. ( I took the old solenoid apart and could find nothing wrong, BTW.) I took the transfer clutch drum off and all looked kosher, but I did not take the assembly apart. When I reassembled, it SEEMED like it was working great. About a day later it was back to its old ways and I got stuck. I just ended up driving the thing in FWD till this December, when I got under it and took off the pan. Some fine steel swarf on the magnet, but not bad for 210k miles. I pulled the filter and flushed it and found many pieces of a plastic electrical connector shell that appeared to be the connector to the part I'd fixed earlier. So, I pulled the tailhousing back off and, OOPS!, the connector had got tangled up with the parking pawl cogs. So maybe that explained why it seemed to work briefly. So, I put it all back together, glued the connector. And it still doesn't work! I put a tester on the TCM wire that controls the transfer clutch and seems to get no signal.( This with the car up on 4 stands and someone else pushing the gas pedal and applying the E-brake. It seems like this scenario would make the transfer clutch apply as the TCM should think the front wheels are spinning and the rear have traction.) What's next? VSS's? If you know of any other forums that might help me more, please let me know. Thanks, Al Replies to this message: samiam_68 (Jan 11, 2009 9:23 am) albrase (Jan 11, 2009 9:40 pm) samiam_68 (Jan 12, 2009 9:37 am)
