Jeep specific tools?

[txj2go]

Looking at the contents of the official Jeep toolkit I see all metric sizes except for a 13/16" socket- what in the world would that be needed for? Also I've heard mention of 12-point sockets needed for a few fasteners, does anybody know the sizes needed in 12 point sockets? I normally only buy 6-point sockets because they are significantly better at transmitting torque to tight fasteners.

check your brake caliper bolts....take a 12 point 13mm

Aren’t 13/16 and 21mm wrenches and sockets extremely close in size?

I would guess that if Jeep specifies a 13/16 in an otherwise metric kit, there's probably a good reason. It is just about 1/2 way between a 20 and 21 mm socket. Usually, you can get away with a 21 mm socket, BUT it might be a fastener that requires some torque. If so, using a loose-fitting 21 mm might run the risk of rounding off the fastener.

The machines I fix at work are mostly metric, but I had to request a 59/64 combination wrench for one set of nuts. A 23 won't fit, and a 24 is too loose to grip the nut effectively. Why did the manufacturer use SAE for this nut? And why an oddball size like 59/64? Go figure...

I agree with you on this one…but…it’s interesting how we pick and choose things where if Jeep engineers did it there must be a reason or Jeep engineers are idiots

Dont suppose you would be willing to share that sheet? Ive been meaning to put together a tool kit for the Jeep and every time I start I just get frustrated and give up lol

Sure, I've seen other copies floating around on here somebody else made. I copied this info from the AEV lift install instructions. I also replaced my trackbar bolts with an SAE size but I can't find what the size is =/

Awesome this at least gives me a starting place to sort and figure out thanks!

You know the ol' saying, "the sun shines on every dogs ass some times". I probably saw it on the internet somewhere.

Me too and I think about it every time I work on my Jeep. Smart is actually finding it or making it.

I thought it might be a case of them buying a component from a supplier that just happened to be SAE size, I just wondered what it was and if I would have to mess with it while on a trail. If it's the track bar then I've replaced one of mine with 9/16" hardware which reminds me I need to get a socket to match that bolt size.

If you start chasing this you get into a small rabbit hole. There are spots where metric and SAE are almost identical. If a person is putting together a toolkit to tackle everything you don't have to have a full set of both, you can figure out where one size or the other can do double duty. In reality not all of the metric sizes are commonly used so it isn't necessary to buy a set with no skips but sometimes you find surprises and you need a tool that isn't in your set. My old USA Craftsman tools didn't include 18mm, a size which is definitely used in the Jeep. In the early 1970s I had a couple of friends who occasionally worked on foreign cars. They said most of the time they could get by just fine with SAE tools. Also back then a lot of tool brands were not made to very good tolerances and fit the fasteners pretty loosely. Today manufacturing is better and this is why a lot of people get by with real cheap tool brands.

In the case of a 59/64, it could be that a tool brand with tighter tolerances would have a 24mm that would fit better. Or a chrome socket vs. an impact socket. Or it's possible that whoever manufactured that part just made it undersize or oversize on the tolerances.

I have found a couple of versions of that on the internet. If you are just considering fastener sizes like I was that's why I was looking at the tools included in the official Jeep tool kit.

That's no help. He can't determine if the fastener is metric or imperial so he wouldn't know which adjustable wrench to buy.

Plus make sure you get the left handed adjustable wrench if appropriate
