I've done abit of a search on the forums to work out what the problem is and i think my rear d/s strut has given up the ghost.

the problem i have is on straight flat road at low speed theres a rythmic knocking sound comming from the rear. i grabbed the rear wheel and gave it a push side to side and theres a knocking noise asif something is loose when nothing is. I've got raised springs in the rear on new kyb's. I'm thinking the strut valves have broken.

Anyone got any ideas or heard of similar happening? only other thing i can think it might be is a loose cv bolt or busted wheel bearing.

Thanks guys

Does the noise happen when you go around corners?

Or only on a straight flat road?

Could it be something loose/broken in your diff, maybe?
 
As it's rhythmic I would initially suspect a wheel bearing.
 
I dont think its the diff, but i have some spare diff oil so i may as well change it over and check for any exessive fillings (last oil change was 1500km ago) just a pain in the bum getting the diff gaurd off.

what would be a way of checking the wheel bearings without pulling off the hub if possible?

its only happening at low speed straight or flat, over 35-40km/h there is no noise, and the noise is only present under acceleration. a very rythmic knock knock knock very low sound.

EDIT:

Well i've been down the car wash and washed the remains of the last bog hole off the rear of the car, and driven around trying to work out what this noise is like a mad man. When i turn its knocking and then continues to down the road 20-30m's untill im back to about 50k's. or just on flat road when accelerating

Perhaps one of the rear tailshaft universal joints? Centre bearing?
 
theres a good chance it is a cv. there is latteral movement in the wheel so im thinking either cv wheel bearings or again the strut valves have given up. I did notice the swaybar links are rooted when i was down there since there is only play in the right hand rear wheel i doubt its the bushings, but i'll replace them as well. Just debating if the cars driveable or not atm.
 
If there's lateral movement in the wheel, look no further.

Not being a betting man, I'd be prepared to bet that the wheel bearings are stuffed on that side.

It could be one of the various suspension mounts; but far more likely to be a wheel bearing, IMO. And I'll also bet that I turn out to be wrong ... :poke: :rotfl:.

Are the bolts at the strut top tensioned up to the correct tension?
Any sign of movement at that end?
 
the strut bolts are tight enough that when i went to re torque them i snaped a socket. looks like i'll be pulling the hub off and taking it to the mechanic
 
That's a bugger, ID.

One of the things I really like about my Sidchrome tools is that they were made when Sidchrome gave a lifetime guarantee on their tools.

Not one of these modern "lifetime guarantees" that are next to worthless.

I took a 12" extension bar into Repco in Melbourne some 30+ years after I bought it from Repco in Brisbane, and they replaced it with a new one - free of charge; no questions asked.

Good luck with the hub. I hope it is something as simple as a wheel bearing.
 
Yea me to the high country trip already claimed the exhaust resonator.

Sounds like a wheel bearing too me.

What a coincidence. Mine got broken on the Bunyip SP and Noojee outings in Jan 2012. I had a new torpedo resonator cut in just before Christmas - $130.
 
Yea i was attempting to straddle a rut that collapes on rams horn track, and put a big dent in the 3'' hot dog. Theres no hole in it so its all good for now. I usualy go to a mate's shop in sunbury i think mine was $95 installed.

Havent started on getting the hub out yet, how much is the cost of the bearing?
 
No idea, ID. Sorry.

Your model possibly has adjustable, serviceable wheel bearings, but I don't think so. I know for a fact that the later Foresters don't, but not sure about the SF series.

Anyone know?
 
i dont think its adjustable. i got one quote for $130 for the bearing alone and have proceeded looking for others. seems abit much for a bearing imo but i could be wrong
 
I've looked at the service manual its a **** of a job, I'll just take the hub to the local mechanic and have him press in a new bearing.
 
^ What I did was take the hub out myself which took me 30mins. Took the hub to a mechanic with a new $70 bearing from repco. Cost me $50 in cash and he pressed in the new bearing. 30mins to get it back in and I was off :iconwink: :biggrin:

It's common for the rear wheel bearings to go on the 1st gen Foresters, especially on the passengers side of the vehicle.


You'd hate to drive my Forester, theres more noises and rattles than you could count. Feels like it's going to fall apart, really it does :lol: I just turn up the stereo and ignore them, non are major. Just worn out or loose things.
 
New bearing in, ended up taking the hub to my mechanic and just having him change the bearing and seals $110 all up but he forgot it was in the workshop for a day

Glad it's sorted; reasonable price IMO.

NOW the important question - Has the noise gone away? ... :iconwink:
