Roars a little and a little vibration also kind of hops a little when backing up incline parking brake doesn't seem have any tension on it not sure if it's rear end or possibly ebrake hanging

My 2004 Jeep Liberty goes in reverse but only goes about a foot in drive and the back tires lock up. No one knows whats wrong or how to fix the problem. Death trap! I almost got killed!

I have a 04 jeep liberty 3.7 liter 2wd and I was wondering if it can be switched to a 4wd same engine

would like to by pass the compressor and get the jeep liberty to run again

I Replaced the bulb, checked the fuses, I discovered there is no power to brake light lens assembly.

Backup light and turn signal work fine..

Can light assembly be bad and how do I check it to be certain?

I have tried a few ways to reattach it but it just falls and rests on muffler making a rattling noise. a few people said I don't need it and to just remove it.. Safe?

Also when you turn off car engine keeps running

My oil smells when the engine gets hot. I was told seeping hose, what hose could they be talking about?

When driving it suddenly seems like its in nuetral and wont move ,but if i turn it off & back on it will go for about a block. We changed the valve body and it still does the same thing. What else can we try?
