Front DS Slop??

AT tires hum a little bit and MT tires hum a lot. There is no getting around it. It's the price you pay for big gaps between the nobbies. Super Swampers absolutely Howl!

I would try to borrow/swap in some simple stock sized radial tires first, if the noise is still there = not the tires.

Maybe install a set of Al's new upper A-arms?

With a 2.5 or higher lift, these A-arms should let the alignment shop get the numbers exactly right rather than "within" acceptable values.

True but I am having the same noise issue and can not pin point it either. I know it is not the tires, totally different sound. As far as as addin in AL's arms the shop couldn't get mine back to factory specs but they were able to get it to drive straight and true. If I get a chance this week after work I am goin to pull the front drive shaft to see if that is the problem.

PSINSYD did you ever get your new DS installed and if so is this mystery noise gone now?

I just had my tires rotated & re balanced this weekend & it has gotten somewhat better but not awhole lot, I'm also going to keep an eye on this thread to hear about any updates

on a side note I wonder if I ruined a rim somehow almost seems as if it's in the back now well at least part of it or what ever is going on up front ruined a tire & that tire is on the back now ???

this is weird, I'm not mechanicaly inclined so I'll wait to hear about the driveshaft stuff from you guy's

I am picking up the libby tomorrow night. I know, I know, why didn't I just swap it myself, but work has been unbelievably busy, and I really didn't feel like dealing with pulling it out again like I did a few months ago.

When they pulled it to see if it was the cause of the noise, it was TOTALLY gone. Now that the new one is in, I will be picking it up tomorrow night and driving it around a while to verify it's gone. I'll try to post the update as soon as I get home tomorrow night.

I think that's what my noise is just haven't had time to remove it and test drive it. Let us know what you find.

Good stuff. If this is the problem, since my rig is still under warranty the front ds should be covered, right?

psinsyd · **Posted:** Thu Nov 08, 2007 11:38 pm

Yep, 'twas the front driveshaft causing my nice noise/knock. New one on, and not a peep from the front now. Drove it home and not a single noise to be heard. I'm really glad that one's finally over with!

I do have the old one that I'm going to see if I can take apart a bit to see exactly it wore.

For those who may be ordering, I would have to recommend worldpartsexpress.com. They had the best price on the net that I could find, and that site was recommended to me from a fellow LOST'er. I placed the order, but I didn't have the VIN on me. They replied back and said that the driveshaft was for a manual and just wanted to verify that's what I wanted (I didn't think they offered a manual in '02). I sent the VIN, and I get an email with the subject "price adjustment"....ugh. To my surprise, it was CHEAPER!! WooHoo!

They were in constant communication regarding my order, continuously updating me on my order status. Great customer service. Basically got the driveshaft for just over $360 shipped IIRC.

Hope this helps you guys out there! Kolesy, if it's still under warranty, I would think they would definitely cover it.

Funny thing was, when I was at the shop when I dropped it off, I was flipping through their magazines, and there was an article on someone who had a Grand Cherokee that was doing the same thing, with the same mileage, and ended up being ........the front driveshaft.

For putting new ends on the existing shaft, you could also check out Rockford Driveline in Rockford, IL.

I was told by my sucky dealership that the powertrain warranty will only cover "internally lubricated components". They ALWAYS have an excuse not to cover anything.

That's garbage. You would think that the driveshaft would have to be part of that warranty. Maybe try a different dealership and see if you can get somewhere with them. Don't mention that you already went somewhere else, just bring it in and see if they'll swap it under warranty.

You COULD also try and argue that the driveshaft is technically internally lubricated, since it does have grease internally packed in internal joints of the shaft. :twisted:

Also, corwyyn supplied me with a link of a company that has used ones that have a 120-day warranty. I think he said that they were going for right around $95 there. The link is www.precisionteam.com.

Hope this helps a bit!

well I did a short test with mine today

while driving up my street i put it in 4 part time ( only 4 hi I have) & came to a stop & low hum noise was gone, put it back in 2 WD & noise came back, so I feel I might have a bad driveshaft also

I would love to take it on the HWY & do 60 - 70 in 4part time & see if my vibration & thumping on the floor goes away but I don't want to blow it up

so looks like I have to save some cash & get a driveshaft

Well, I ended up jinxing myself I guess. All happy after picking up the truck on Thursday......just for the noise/knocking to come back today. Ugh, at a total loss now. Not sure what it could be now, since it totally went away with the front ds out....transfer case? Sure hope it's not something like that. Hmm, trade-in time? I really don't want to.

Raceinfan, the P/N I have on my invoice is 52111597AA...not sure if you still want to buy one after hearing my latest update though!

Keep us posted on what you find, cuz I'm just about out of ideas and am pretty much done with dumping money into the 86k mile KJ! :wink:

Thx SD-KJ. Mine is more of a knocking that starts right at about 45mph. I'm thinking about trying the 4wd test next to see if that has any effect on it. Since it's dry, I'm going to have to find a nice long straight to try it on.

raceinfan · **Posted:** Mon Nov 12, 2007 5:12 pm

next monday mine is going in for the fluid changes & they told me they'd take a look see in the front diff to see if anything is wrong

it acted up all day yesterday & today took the service mngr. out for a run & wouldn't ya know it NO NOISE OR ANYTHING

I'll keep ya all posted if anything comes about

wildrussian · **Posted:** Tue Nov 13, 2007 8:54 am

Well guys sorry I haven't posted in a little while but I didn't have time to take my drive shaft off this weekend. I had lots of stuff that came up and no time to tinker with the Jeep. I will try next weekend and see or if i get a chance I will drop it off at the dealership and have them listen to it and maybe they will tell me whats up.

wildrussian · **Posted:** Wed Nov 21, 2007 1:30 pm

Well I just got a call from the dealership about my noise. First time they called they said it was the front driveshaft making the noise because of the lift so I told them to take it off and drive it without and and see if the noise goes away. They call me back later and say that they can't drive it without the front driveshaft but they had the service manager look at it and he said it was the rear driveshaft making the noise because of the angle where it goes in rear differentail. He said they had it on the lift and the angle looked to the side or something like that. He asked me about the lift and recomended I get something to straighten out the angle. I knew better then to take it to the dealership but I thought I would try it. I guess when I get it back Ill take the front driveshaft off myslef and see. Im getting really frustrated with this stuff.

The lift did not change any angle of the front drive shaft becuase the front diff is connected to the cradle. It's in a fixed position just like the transfer case. I have the same noise you're talking about. I just changed the front diff oil last weekend and it came out looking silver. Starting to think i have bad pinion or carrier bearings in the front diff.

OK, that does sound reasonable since lifting the KJ does change the rear angles. As far as not driving without the front driveshaft that is complete hooey - when I had to get my new front ds I took mine out and drove for a week before I got the replacement. The two companion flanges that the ds mates to are held on with large nuts (like 1" or better) and nothing is going to walk out of the front diff or the t-case. Of course it's about what I would expect a dealer service dept. to say :roll:
