If the steering wheel is turned to full lock position, the power steering system is being exposed to thousands of PSI for a brief moment until the pressure relief valve kicks in and allows pressure to bleed off. Which is the hissing/groaning noise you may have heard before. That brief moment of extreme pressures is the most common causes of failures in power steering pumps along side dry steering while not moving. If you have shudder going both ways, you will need a new power steering pump because it is worn out. If you get a shudder in one direction and not the other, then you will need a power steering "Rack and Pinion" assembly. If it was my car, I would do both at the same time so you don't have to worry about the other component going out later on and starting the whole process over again. I hope this info helps!

SOURCE: engine timing for a 1998 subaru forester with a 2.5

Since ignition timing is taken care of by the ECU, I guess you are asking about cam timing.
There are several marks to be aligned and if you get them wrong, you may trash your engine so I am only going to suggest you buy a Haynes service manual that has numerous good pix that show you exactly how to avoid killing your engine. And, unless you have a good-size vice well-mounted, compressing the belt tensioner again is going to give you fits.
The Haynes number you need is 89100 but it is listed only as a manual for the Legacy which uses the same engine but there may be less info that is usable on your '98 forester for which Haynes does not make a specific manual.
The later book that I have, 89101, covers all models from 2000 to 2006.

SOURCE: how do i bleed my power steering rack on subaru legacy rs turbo

A power steering dosent need bleeding. If you replaced it a week ago and was fine until now then it's not an air problem. Power steering fluid is pumped through the system even when the steering is not being used. Definatly not an airlock problem. Cheer's

SOURCE: where is the re-set button to program a remote

Obtain all keys/remote controls. Remove driver's side kick panel/lower 'A' pillar trim. Connect central locking registration connectors (white) - black wire and black/blue wire Fig. 2 . Unlock the vehicle using the key. Program first key/remote control as follows: Press unlock button Fig. 1 [1], then lock button [2]. The door lock should lock and unlock in sequence confirming programming of first key/remote control. Repeat programming procedure for remaining key(s)/remote control(s). Once the last key/remote control is programmed disconnect central locking registration connectors. Check operation of all programmed keys/remote controls.

I have accidentally put petrol into my turbo deisel forester, it now has 30 % petrol in the tank, will this cause any damage and will I be ok if I start to run down the fuel and add more deisel ?

Yes, this can damage the engine, do not run the vehicle. You need to drain the tank completely, as well as drain the lines and may even change the fuel filter.

Why do i have low power on the subaru forester 2003 when its hot?

There is an air sensor on your air filter intake. I would first suggest having this checked for proper function. There are other sensors that can also be checked. Your problem does not sound mechanical

Sidebar: I have always used full-synthetic oil for turbo-equipped automobiles.

My 1998 Subaru Forester steering wheel locked while I was driving and the brakes went out also.

I agree with the other Expert, but the steering wheel lockup is puzzling. Do you mean it did not turn or was hard to turn?

Now if the steering wheel locked in its Parked position, then the Ignition switch had to allow it. It would be consistent with losing the electric feed to the motor and things the other Expert said. Your Ignition switch may have turned itself off. Sometimes too much weight on a keychain is enough.

If the car will start, it may be okay. But the inside of your Ignition may be coming apart or your Keychip is cutting out. You might want to change Ignition switches.

I have just purchased a 2004xt Forester when i first start ( cold start ) it will make a noise like a grinding / gear drive noise for a couple of mins..the noise does fade as the car warms , but is still...

Could be several souces:
1. Check the alternator and AC belt idler bearings. Replace as needed.
2. Check the alternator itself for noise and bearing wear. Replace the belt if needed.
3. If very cold (below 0C) the power steering pump make a lot of noise for a while (30s to 2 mins) till it all warms up.

4. If the above are OK, then the next is the timing belt idler bearings.

1995 subaru impreza wrx sti overboost problem

I bought a 1995wrx turbo japanese import 260bhp standard,which can only run on v-power 99octane fuel,from scooby clinic in chesterfield (scooby race tune expert mechanics).I was the first person in england to test drive on road (it had not long arrived in the uk & had been put on rolling road a few times),whilst test driving,the turbo boosted normal & then started juddering slightly etc etc,i asked scooby lad "what was that" he wasnt sure(office boy!) & assured me that whatever it was theyre top mechanics would sort it out & do a full service,change the belts etc etc, ...so i bought it,luckily with a 30 day warranty included starting from collecting it.I picked it up about a week later,i got as far as 20mile away(nearly home) & it started juddering again,nothing too serious,so i thought we'll see how we go.next day same again,after 3days it were juddering more visciously,getting worse to the point where i nearly hit the windscreen,i thought its got to be a fuel blockage?.it backfired twice & not long after that packed up & would not start again,i foned scooby clinic & towed car back up to chesterfield.they kept saying "i must of put wrong fuel in",they ended up taking engine out cos head gaskets had blown,engine had died,6-7 wks later they told me to come & collect car with no charge,i was told to run it in for 500 miles steadily,& then take it back,they then changed oil,sparplugs & boosted turbo back up(re-connected it),the boss apologised to me & said if he knew it were like that he would never have sold it at all to anyone,he explained that the engine was carboned up(blocked) they did a nearly full engne re-build free of charge.the boss said if he knew it were blocked up they would of gave it a thrashing to clear the engine.
