Lobro spline bolts '89 Audi 100 (tool size)

Oct 27, 2003 3 Replies

Can a kind person confirm the spline bit i need to 'invest in' as being a M10 12 point please.



I assume a nice long one to clear the inner CV boot would be a good idea, say a M10 x



100 and i can drive it with my 3/8" socket gear?

Also, what is a good quality brand.... most of my tools are Koken but nothing on their website says they make a spline bit.



Thanks Pete


The tool you are looking for is called a TriSquare (or various variations thereof). It you use that term at a tool shop or car place they should know what you are talking about.

For the record and anyone else who needs to extract the axles for cv work or the transaxle, the LOBRO cap bolts are M10 12 point SPLINES. A long (75mm) spline bit driver to 1/2" socket connect is handy too as it helps clear the cv boot and reduces chance of boot damage. Japanese tool company SEK produce one.

Warning: if the bolts have not been undone since new they will be very tight. Clean out their head of all grime and road dirt to assist a good fitting of the spline driver. Use a long breaker bar socket driver and plenty of extension to clear the car's under pinnings and expect a shock to the hands when the cap bolt lets go with a bang.

AKA "Star" bit, not to be confused with a "Torx" bit. Most of the parts houses knew what a star bit was, but not a "spline" bit. Don't invest a large sum on it, since it will probably become another use once tool like so many others in my garage.
