Z3 Differential tool

Where do I find a 14mm differential tool...in other words a 14 mm hex (allen)head socket 1/2 inch drive for a "reasonable" cost?? I am about to change the diff. fluid and replace with a redline product. Maybe someone has one f/sale?? Please advise. Thanks!!

I found mine @ Autozone.

Still had to cut about 1/2" from the hex so I could use a rachet.

Just DO NOT tighten them upon reinstallation to the factory torque spec of 75Nm. Several people have cracked the cover BEFORE reaching that value.

I only tighten them to 45-50Nm, and haven't had any leak, crack or come loose in the past nine (9) years.

Buy two (2) new replacement sealing (crush) washers and reuse your existing plugs.

I just bought a 9 piece metric set from Harbor Freight. It is made oversees, but for $12.99 (sale price), you get 4 to 8 mm and 10 mm - all 3/8". Then you get 12, 14 and 17 mm - all 1/2" drive. For once in 20 to 30K miles, it should be fine. Link below:

Sears also sells these on-line. See following link:

Different pic from what I got from him.
Not many will pay for that.

That was certainly the first one I knew about, but several more since then, judging by the number of people that have wanted the take-off ///M covers. These were owners of ///M cars, not Z3s doing updates.

Gentlemen,

How crucial is it that a "stuby" socket be used? If that is the case then I should be looking at the Facom tool or the Stahwille. But do they have them in a 1/2 in. drive cause that's the size of my torque wrench. Please advise.

Nothing but a "stuby" socket will fit, specially with a torque wrench.

I posted the STAHLILLE socket since it's like the FACOM one and some may want to purchase it.

The FACOM is a 3/8" 14mm for the diff.

The STAHLILLE is a 3/8" 7mm for the caliper guide pins.

......................................

You need more than one torque wrench if working on a car.

I have a 3/8" - 25 > 250 inch pound one along with a couple of 1/4" lower inch pound ones.

I have a 3/8 - 5 > 80 foot pound (one I use the most)

I have a 1/2" - 25 > 250 foot pound (lug bolts)

......................................

If you have the room you could use your 1/2" torque wrench and a normal 14mm hex socket.

Hazet offers a 14mm hex in 1/2" drive: http://www.samstagsales.com/images/hz985-14.jpg
Unlike the E36 the E36 Z3 M Roadster/Coupe does not have a clearance issue with the top (fill) differential plug, therefore, you don't need a stubby socket.
Clearance is also not an issue with the side mounted differential plugs on the Z4M. The Z4 transmission plugs are a different matter. They require an 8mm hex and the top (fill) plug has minimal clearance. I use a Matco stubby 8mm hex P/N BXYS8M to access the top plug with a torque wrench.

Less than the Snap-on one. What's the over all length?

Thanks for everyone's advice/help...today looked at 3/8 socket wrench....think I will go with that and get the Facom 3/8 hex socket....much easier than trying to find a 1/2 in socket to fit my torque wrench.
