So I go to replace the rear wheel bearings on the car. And I find out they use a 15MM Allen head bolt on the bolt that holds the hub on. Does any one know where I can find the right wrench. I have searched everywhere in my area and the Internet and the biggest anyone has is a 10mm. I can't believe something so simple is stopping me[:@]
Car is a 98 A4 Quattro

 

that's a big Allan key mate try some shops or the garages might be able to help/rent/lend you one

 

A hardware store. It most likely wont be the allen key type, but a socket set... Like this:

I looked at 3 different auto parts stores in their tool section, and i finally found a hardware store (mostly industrial tools) that carried them. I would imagine that Sears hardware would carry them too, did you try there?

 

its not 15mm its 14mm.. so dont get the wrong size.. and good luck trying to find it I ended up making one.. took a 14mm bolt and weilded it on a socket.. no one had one.. I just did mine..

 

You should really buy a allen socket set though cuz there are several locations where you need 10-15mm sizes. I like bravos idea though, crafty and free.

 

well all the kits i found at local places only went up to 10mm.. Sears, Home depot, Lowles, and a few hardwear stores, Nappa, pep boys, car quest.. no one stocked that size.. but they could all get it. so I just said f-it wored fine.. weilded it to an impact socket worked perfect..

 

For DIY wheel bearing don't you need a press as well. Just thought I would bring it up. There has been no mention of it in this thread.

 

He's doin the rear not the front

 

I just got my rear wheel bearing replaced. You do need a press to get the bearing out.

 

Yes you need to press the bearing in. I already have the tools rented to do that. I also made a tool like mentioned above but it looks like the previous owner had tried to do some work there and messed up the hole a little so I couldn't get a good bite. But there is 13mm hole in there also but I was hoping to use the right tool on that one because most bolts that have a 13mm head on them are not the strongest bolts and I'm scared I'll just brake it in half.
