I just noticed the other day that I have an oil leak in the rear end of my 04 scab, looks like its coming from the front where the drive shaft bolts on, anybody have this issue with theres ? is this a big job to fix?

 

Pinion seal leaks aren't uncommon at all, in any vehicle. Just drop the driveshaft, remove the nut, pull off the drive flange, replace the seal, replace the flange and nut, and try to get the nut torqued as close as possible to where it was, replace the shaft.
