Components replacement timetable project


Recommended Posts

The idea is putting up a list of different components that sooner or later will fail on a Subaru and find out statisticaly at what mileage each of these components will likely fail. The purpose being to unable those that hate to be stranded in the middle of nowhere to make repairs or replacement before the components actually fail.

If enough people volunteer information, and if Josh pins this thread down for a while, I volunteer to make a resume (in a single post) of it all when the time comes. It then could be put in the archives.

To keep it simple, we might leave out items that were the objects of recalls and stick to "normal wear"..

- coolant temp sensor : 165,000 kilometers on my Loyale and 170,000 kilometers on my Legacy.

- alternator

- seals

- bearings

- sensors

- etc.

I'll jump on your bandwagon in order to get things started, though I'm not sure that it will turn out the way you plan. I've got to believe that Subaru uses its dealer feedback on warranty issues, etc., to better those problem parts. For instance, my 2002 OB Ltd is by far a superior vehicle in almost every way than my 1997 OB Ltd. Subaru really improved this model's ride, handling, creature comforts, etc. But that aside......back to your project.........at 64 000 km one rear wheel bearing ....... and piston slap starting at 24 000 km on a 1997 OB.

from what i have experienced, the oil pump seal and the seal around the back plate are what cost the most severe hassle. Especially the back plate, because the motor must be removed to reseal. My buddies 96impreza had the backplate seal fail around 120k miles. The oil pump seal failed on my 98 impreza almost exactly at 70k miles.

 

my gfs legacy which is 8k miles from 200k is running like a top.

 

bearings seem rather unlikely to go bad.

 

Are there any sensors that go bad? I was going to do up a custom exhaust system myself, until i noticed there are 3 oxygen sensors in the system. I was under the car with a 6 inch fiber disc and everything ready to go to town. Maybe there were only two, but im pretty sure i remember seeing three. Which was more than i wanted to deal with. Is there a purpose for each? how do you know if one goes bad?

 

The AC pump is made by calsonic and looks like it wouldnt be out of place in a large truck, the alternator seems to be of similar quality. Has anybody had an alternator go bad?

 

Thank god subaru doest use a mechanical distributor. I wish certain other manufacturers would buy a clue...

 

data organized in something like a spreadsheet with what ppl report would be interesting and would aid in what to keep an eye on.

 

On another subject, has anybody seen a mastercylinder go out of adjustment on a subaru? My bro is experiencing that right now with an integra. There is a push rod that somehow streches or something and takes up the freeplay in the pedal causing the brakes to stick on.

 

Are there any common problems with older auto trannies to watch out for? gf's legacy is a 90 auto.

gbhrps,

Everything's welcome, but i was mainly tinking in terms of components that can leave you stranded when they fail without warning.

You're right in pointing out those improvements but I think (but may be wrong) that sensors, alts, pumps, etc. tend to stay the same from MY to MY. The fact that the coolant temp sensor on my 92 Loyale and on my 96 Legacy failed after the same mileage seems to support that opinion. But there are certainly exceptions.

ADDITION : clutch pedal starter defeat switch failed at 180,000 kilometers.

There should be 2 O2 sensors. The front one is what tells the ECU to add a/f corrections. The rear one is solely a cat converter efficiency sensor.

 

I've never heard of a MC problem like your buddy is having. yes there is a Rod that pushes on the MC, but unless it was backed up in the MC, there shouldn't be any problems.

 

Yes older auto trannies have issues. The auto tranny was updated & revised in 92. However even some of the 92+ ones have issues.

 

All depends on how you drive and how it was maintained.

1997 OBS MT (118K)

~80K- Rear wiper

~85K- Rear Defrost

~87K- Rear washer

(eventually all of above found to be caused by cracked/broken wiring between rear hatch and body)

~80K- Heater Fan resistor pack failed.

~90K- Oil leak from timing belt cover.

 

 

1992 Legacy L 4EAT FWD (118K)

 

bought at ~95K.

~95 K inner CV boot replaced.

~97 K left rear brake caliper replaced.

~113K- Right front Wheel bearing replaced.

~115K- Coolant tempurature sensor

~117K- Fuel tank fill tube leak. (due to undercoating)

 

only one to leave either car stranded was the coolant temp sensor.

i had an igniter (controls the coil pack) go on my 92 awd sedan at ten years / 220k km from what i could see when i opened it up there was on jumper to the circuit board that was not covered by the gell and it had corroded so it might have been a one off ? and the same week a freinds forrester had a similar problem at 120k km

regards camo

my 95 Legacy with 2.2 L and auto tranny had the water pump go bad at ~ 110k. The oil pump o ring developed a leak when I switched to synthetic oil.

54000 miles Extension housing - torque bind

54000 miles front left wheel bearings

54000 miles rear differential

70600 miles oil pump seal

70600 miles crank shaft seal

70600 front right wheel bearings

76000 miles rear engine backing plate

76000 miles extension housing again - torque bind

83800 miles rear diff again

90500 miles front left and right wheel bearings again

90500 miles front right inner C-V boot

90500 miles rear diff again

 

Mine is probably a severe case of a bad car going badly wrong. I've left off the other stuff replaced because of dealer incompetence, such as an entirely replaced transmission, 2 other rear diff (5 in total).

97 OB 4EAT 90500 miles car still in shop with a suspect extension housing again due to torque bind - this is 3rd time.
