Post subject:  Front drive shaft??
Ok, for the past two weeks or so I have been hearing a noise which sounds like something metal loosely scraping on something else metal as I drive. I knew my brakes were due so I assumed it was that, I went and got new brake pads and installed them and I still got the sound. Been really busy and havent had time to check it out closely but today, I started to get a thump thump thump as I drive. Not always, sometimes louder while I'm turning. It definitely increases in rythm as I speed up. So I crawled under the jeep to have a look and there is no rubber boot where the front drive shaft comes out of the differential... I'm thinking that is bad, no?

So what kind of trouble am I looking at here and how much to fix it? Can I just pull the front drive shaft as a quick fix until I can get the parts to fix it properly?

does the front driveshaft spin even if it isnt in 4 wheel that would account for the noises I'm hearing?

I don't know if it's the noise, but it does spin in 2WD.

Ok, so I got the driveshaft out and that solved the scraping sound but I still have the thump. It seems to be more pronounce when I turn left and it is a solid thump that I can feel. Any suggestions?? Ball joints maybe?

I would check both your CV half shafts. You might have a bad CV. Check the boots for any rips or tears and greas spots.

Chances are you have a bad drivers side CV. Aftermarket about 100.00
MOPAR 350.00 and up Easy job if you done it 5 times (LIKE MY SELF)

You can buy CV's from NAPA, just make sure you buy the remans not the Chinese stuff.

Post subject:  two boots?
I assumed that the front drive shaft had two boots on them, one near the axle and one near the t-case. When I pulled mine out, there was only one boot, near the axle. The end near the tcase was all gunked up with what I assumed was dried grease mixed with dirt and sand (lots of beach driving).

Now that I have been looking for a new drive shaft, all the pictures I see Image only show one boot. So was my assumption that I am missing a boot on the rear of the driveshaft wrong? And if so, what can I do to service all that gunk so it doesnt sound like Im sharpening something on a grinding wheel when I drive? Can I just scrape all the gunk out of there and pack in some heavy grease or something?

There is a boot on the rear as well if yours is missing then you need to get a new shaft or rebuild the one you have. Pictures do not show the rear boot as it doesn't look the same as the front one. Its more of a concave deal that sits back in
