I just install a 4wd shifter bracket last night to correct my issues with going into 4lo. I put a 4" Rough Country lift on about 3 months ago and I couldn't get into 4lo so I had to install this shifter kit. After I put this kit on I'm gettin a strange knocking shound from around my transmission/transfer case. The sound only happens for about 3 seconds when I take off in 1st gear. If I put my jeep in 4hi I don't hear this sound. The knocking sound is not very loud but I can hear it. I was wondering if anyone might know what causes this and how I can fix it.

is the shifter hitting the tub? look for shiny or dented metal for clues to where it's coming from.

i chased a knocking sound for quite some to find it was the cat hitting the rear of my skidplate while taking off.

That’s a good idea. I guess I should start looking small before I start thinking of the worse.

I ran into the same problem on mine...only happens in 1st gear and if im on the gas hard while taking off or lugging the motor. Sounded kinda like a ujoint popping. Something hitting the tub is a good idea though...course there aint nothing shiny on my tub cuz its covered in mud at all times. If you chase this one down let me know, reckon its time i started looking into it anyhow.

if it's on your tj check your track bar and drag link bolts for tightness.

scumby will removing the sway bar increase the noise? What do you think?

 

[scumby]

i don't think removing the sway bar will increase the noise but it may help eliminate a potetial source of noise. i ridden in a tj without a front sway bar though

i don't have a tj but know others that do and have found their drag link? (whatever one is in the front) bolts loose. this makes for a real annoying clunk as it slides back and forth in the factory elongated hole. mine was loose a couple of times as well in my yj.

for those with heim joints/rod end bearings on the front steering components i have found that once those dry out they make horrible noises as well especially when turning side to side. a little wd-40 quiets them right down.

I've noticed a little "clunk" with every shift, when I let out the clutch, exept maybe 5th.

Am guessing here, but could my clutch be going a bit sloppy ?

Is a clutch rebuild difficult ?

Never had to deal with this in previous vehicles. New territory here.

 

[scumby]

clutch rebuild or replacemment? i'd just replace it vs rebuild.

just guessing but i would look at thigs that are effected by releasing the clutch. loose bolts on bell housing? notice any vibrations? in 4wd or 2wd or both? u-joint straps loose?

Dang cats! It gets really messy when they get in the fan shroud to sleep and don't get out before you start the motor.

 

[MouthfulOfGrass]

Thanks, now Saturday Morning I'll be under the Jeep checking for loose stuff. The house painting can wait (glad the wife doesn't read this forum).
Got 2 cats, I like one of them, wish the other would find the fan shroud sometime (did I just say that out loud ?). That was a joke ! - for all you PETA peoples. Cats do know how to swim by instinct though, threw 'em in the pool just to check out the theory.

for some wird reason every mourning when i start my TJ it misfires for 10-15 seconds and then just disappears and runs normal...
Today i noticed it on mine that it raddled around the shifter. I'm guessing the transfer case got something loose in it or holding it.. i'm off to search the net now..

Hank, your answer lies here. No it's not your clutch.

Thanks for finding that ^.

 

[Hank]

Thanks willness33, now that I know that it's not my clutch I may not worry with it untill it warms up a bit. This sounds like it could fix my problem.

 

[Triple88a]

Hank does the problem go away in AWD? In mine in 2 wd it knocks and in awd it stops (i cannot hear any knocks)

 

[Mudweiser]

You know after installing the 3" BL drop bracket on mine i should of known to check that. *slaps self in forehead* Thanks for the link, reckon ill find some duct tape and fix that problem.

 

[Triple88a]

Mudweiser,
3"BL? Body lift? thats 7" lift? how is it? What did you do with the drive train vibrations or problems? just transfer case drop or what? Which RC kit did you get X or II?
Thanks

BL= body lift. body lifts don't cause driveline vibrations

OK all today i got my jeep back from the dealer. They fixed the knocking i had (when taking off or when strugling the motor). I believe they said the tranny bushings needed to be lubricated... The person there said they are near the shifter or something like that.
