The rear hub bearings have been replaced twice in 4 years and it sounds like a new set are needed again. Does anyone have experience in this area and can suggest possible causes for excessive wear please?

If the reason isn't constant hard tail-out cornering, it might be a good idea to get the tracking checked.

Thanks for the reply and the suggestion.
That's not my style of motoring!
We bough the scooby for the 4-wheel drive, which is useful in the highlands in the winter and for reliability. The car's just 10 years old with 96000 miles on the clock and runs like clockwork, shuttling me and the family and the kayaks to the river for kayaking.
Now we are looking at the rear diff. and I think this is starting to get expensive.
Will keep you updated.

Has the car been modified with spacers to bring the rear wheels out, or has it got custom rims, not of the original size, or other suspension mods?
|
What's the rear tyre wear like? It's worth having a proper four-wheel alignment check doing once a year on any Subaru.
You may get more advice on the forum on sidc.co.uk

No modifications at all - standard vehicle.
Tyre wear even on all four corners.
Now looking at the hubs and CV joints....

I'm not at all familiar with Subaru's, but it may be the way they were replaced that is at fault. If they are taper roller bearings and were replaced too tightly, ie without a tiny amount of end-float, the new bearings may be destroying themselves from day 1.
Taper roller bearings always need a minute amount of end float, just enough 'loosness' to ensure they dont start to 'clinch' when the bearing gets warm on a long fast journey.

Ah brings back fond memories of the Timken tapered races used in the old Minis, very common for them to be over tightened.

Is it the rear near side wheel bearing?
Having had a Impreza sport (97 vintage). I know of this problem only too well, having had the nearside rear wheel bearing replaced 5 times in 12 years. All other bearings were original. It appears to be problem that only affects the rear near side. Why?
Subaru know of this problem also. There is a engineering notice that says if a vehicle keeps having this issue then fit the earlier model roller bearing rather than the standard ball bearing.
If your previous wheel bearings were fitted by a Subaru garage and you have the receipts, then you might find they will do this upgrade for free if you go via International Motors Customer service.

Finally - it was the off-side drive shaft.
Found a second-hand unit and now fitting it.
if you are told that the Impreza and the Forester share the same running gear - don't you believe it!
Still, the change in the scrappage scheme means the car is now of some value to someone.

Brinneling of bearings can occur due to poor practices during fitting bearings and through poor practices during removal of brake disc.
The Brinnel test is (www.gordonengland.co.uk/hardness/brinell.htm ) comparable to what can happen to a wheel bearing that is abused during fitting (over loading, impacted, missaligned etc) and will shorten the life of a bearing. Brinnelled bearings will have indentations in the bearing surfaces where the ballbearings have been forced into the surface.
