What size wrench for driveshaft?

Dave Meyers · May 27, 2007

I may need to tow my 2000 Cherokee classic tomorrow am. on a tow dolly. Does anyone know offhand what size wrench it will take to remove the back of the driveshaft/U joint? The Cherokee is a 4 door 4x4 with slectrac Tcase and six cyl motor. Thank you in advance. Dave

It's really small. I want to say 7mm or so...(at least at the pinion)

its an 8mm, i recommend a 1/4" drive ratchet with a 3" extension and a shallow 8mm socket, and bring a pry bar to pop it out of the yoke.

but in hind sight to put on a tow dolly you dont need to pull drive shaft unless you have the awd t case. just put the case in neutral and put her up on the dolly.

Thanks for the info, it is too late and too dark to get under there prior to leaving. I'll just pack the tools and head out tomorrow am. I understand you can tow without shaft removal, but I have read some real horror stories even on the XJ board about the process going bad. Seems like cheap insurance to disconnect the shaft and tie it off. Dave

Or a 5/16" - same size.

You'll find out that it's actually a fairly good idea to replace the screws with socket heads tho - that's what I do. Makes it easier to get in there and hit the things, and you don't lose "wrench clearance" going against the strap and cap.

The D35 should be 1/4"-28 - I'm not sure about the ChryCo. I'd figure they're threaded either 1/4"-28 or M6-1.0 - either way, about an inch long should do neatly.

Word up! (X2^)

I use a ratcheting battery removal tool for side-post batterys to take 'em out-- 8mm/ 5/16 and easy to find in the tool box! I now use the same thread bolts with a 1/4" drive allen head (left over from H-D projects) to make life easier in the future!

good luck with it!
