ok, another problem... so apparently the track bar needs to be removed before you can remove the tailpipe on a yj. the haynes manual says that you should jack the vehicle before doing this, do I have to? I'm having a really hard time getting the bolts that hold the track bar in place off, have tried liquid wrench, etc to no avail. Is there a trick to this? Never thought that replacing the exhaust would be such an operation.
