First off I have a 99 TJ and my control arms and brackets are bent. So instead of doing some cutting and welding I found a set of axles from a 97 TJ with the same gear ratios that I currently have for pretty cheap. I am hoping to just swap my axle for this these but I was wondering if there were any differences between the 99 and 97 front axles? Ie the mounting brackets and such. Thanks in advance for all the help.
