Question Lug Nut Torque - MY04 2.5X - Number Is?

I've searched and searched but can't find an answer. What is the correct lug nut torque for a 2004 Forester 2.5X (USA) with the steel wheels? In view of most garages torquing lug nuts to 500 FT/LBs <g>, I'd like to loosen them and retighten to spec. Thanks very much.

62-75 ft lb. I use 68.

Yes, I understand what you mean about the garages. That's why I have an impact wrench--perpetually set in reverse.

Believe it or not it's in the owners manual, the thing is it's buried in a spot that you would not think to look. It should be in the tire and wheel section but no, it's in the emergency section under changing out a flat. I've attached the page just in case you don't believe me I know I looked and looked one time and would have sworn it was not in there. Silly place to only put it if you ask me...

Well, it looks like Peaty's source is a bit more authoritative than mine. I got my info from a mechanic.

But checking my maintenance manual I see a figure of 65.7 ft lb. Clearly it's not required that the torque be controlled to tenths of a foot pound. The actual spec in the manual is a nice round figure of 90 Newton meters, and they just slavishly multiplied this by the conversion factor and didn't realize how silly the result looked.

I think we're all united in saying mid to high 60s.

The Subaru-packaged locking nuts for the FXT say 65, but I use 68. Why 68? Well, I've been using that for years on my MGB so it is easy - for me anyway - to remember, and is good for all three of my cars.

I always re-torque after a car's been in for anything (which is generally tyres, as I do most work myself). I can't help wondering whether places which over-tighten realise just how dangerous it is to stretch bolts (or studs) beyond their elastic limit. Sometimes I've wondered whether I should replace them peridoically, but it's a real PITA to do so.

Thanks a bunch for everyone's help. Yep, I'd referenced the owner's manual without success, never thinking of looking in the Emergency chapter. Lug torque is prominently displayed in my Nissan manual and I thought it odd that Subaru would omit it in an otherwise thorough manual.

When changing a flat tire on the roadside, proper lug nut torque is NOT on my list of concerns. <g> This is great info -- thanks again.

Just curious, but how do they expect you to torque the lugs down to a specific number when on the side of the road without a torque wrench?

You mean you can't tell when you've reached 68lb/ft just by feel??? Geez! Haha.

Your arm is not calibrated like ours?

I carry a small cheap torque wrench I got at AutoZone for just such an occasion :)

I consider myself happy once I get the spare mounted and get back in the driver's seat. Torque? Enough to keep the spare attached. If it's not quite right, Forester won't notice the difference for a day or so, and by then I'll have things back to normal.
