weird ticking under acceleration
 

Hello,

Just recently I heard an odd sound that sounded like the intake tube on the turbo was off. I didn't think anything of it and went to check it when I stopped but the tube was still connected.

The next day a ticking started. It only does it in gear. It also only does it when you have a little more than 1/4 throttle.

My thoughts were to check and try to over fill the tranny because it does have a slight leak in the output side of the transfer case.

I had just read a thread about a ticking and he was told it could be exhaust side turbo bearings? My turbo has very minimal shaft play.

Any help is appreciated!

Thanks

define tick to some people a tick is a knock and a knock is a bang and a bang is a boom if you get my drift.........

a tick is more like a valve clatter sound kinda quiet (usually) is it heard at any point in the throttle or just at 1/4? dose it speed up with RPM or MPH?

Hello,

it is more of a clicking.

I think I have found the problem,

me rear u joint has a ton of slop in it and the boot for the transfer case has a hole in it.

there for the clicking clacking noise is coming through the boot for the transfer case and makes me think it is internal.

Got new u joint just have to put it in and see.

Thanks for the reply though.

Hey, just curious, is ur transfer case linkage really loose? Try moving the transfer case lever just a quarter inch forward when you hear the noise.. Your gears could be touching as you drive causing the sound, if your linkage is sloppy.. Mine used to do this, until I replaced the linkage.

yea that was my original thought but didn't fix it.

gotta change the u joint and see

Thank you,

K,
Good luck man! Hope that does the trick, keep us posted!

Samething is happing to my truck it does it at low speed and speeds up until about 30mph. then goes quite. i think its my u joint it has some play in it. if you replace your u joints post it if the noise went away. i dont want to tear into my tansfer case or rear end.

Now Im worried,

replaced the u Joint, Checked all the others

filled the transmission (not over full but I put 5quarts in because that was all I got.)

And the noise is still there. I tried putting it in 4wheel (with hubs unlocked) and it is still there.
It only happens under load. like if Im going through town the speed limit is 35 so if I coast it does nothing but if i give it throttle to get up to speed it will click.
When you push the clutch in it goes away.

My question is, does the transfer case fill off the transmission oil in these trucks? That may be a stupid question but ive never really worked on the transmission in this truck.

i don't think there is a problem with the transmission. But Im not really sure what is wrong. I tried feeling for vibrations on the transfer case lever and the gear shifter but there is nothing abnormal.

i really hope somebody knows what this might be. if not Im gonna take it to a transmission shop in town to see what he thinks it could be,

Thanks guys

no that transfer case fills from a hole that is on the output shaft of it. i just got my u joint put in gonna see if that was making the noise. if your truck has a slipe spline check it gor grease or play cause that can also start to make a squeeling noise.

that is what I thought,

I need to take it for another ride i had put 3 more quarts in.
I can't visually find anything loose sloppy or whatever.

Could it be in the rear end? like teeth on the ring gear. But that wouldn't make sense cause this only does it at road speed and only under load.

ill have to double check everything again,

thanks

Check your exhaust gaskets at the engine...

this seems to be more than an exhaust issue i think. Ill take a look though.

the sound it makes is like a snap and a click at the same time. like something hitting on something.

I really thought it was the ujoint because it was in really bad condition.

the rear end usually makes a clunking noise and you can feel it. i just put my drive shaft on my truck. cleared the noise right up and greased everything while i was at it. hopefully you find out what is making the noise and hope its cheap to fix good luck.

the rear seal on the transfer case has a seaping spot. the shaft has very little play around the rear of the transfer case. I can see my new fluid is seeping out of the seal.

the slip joint has a small amount of play in it as well.

do you think this little bit of play on the rear bearing is making the clicking?

I tried the truck in 4lo hubs not locked in and the clicking fades out but Im guessing that is because of the internals of the transfer case are moving slower. so that would lead me to believe it is not in the transmission which is good.

let me know your thoughts on the rear bearing and the slip joint. It prolly moves less than 1/8th of an inch ( the transfer case bearing ) the slip joint doesn't move that much but you can feel it wiggle.


Thanks

i had a 97 (2nd gen) did the same thing for along time!!!! and now im facing parting the truck out... im not sure what happend but the ticking got worse and became a knock and now no more truck... RIP 97 DUALLY

FIND THAT TICK

Yea that is my fear. I posted on pirate 4x4 to see if they had more input on the transfer case because that is their thing.

Im going to get the tick figured out. tomorrow im going to the transmission shop and see if he has time to take a ride and see what he thinks.

thanks

Carrier bearing if equiped can make the noise even if it looks good from the out side but other then that a dunno. open up your rear end and check the teeth. then tear open your transfer case, its not hard. they are very simple just get a manual or find one online. Good luck

Oh I know all about carrier bearings.

I used to have a sencond gen ex cab long bed lifted 6".

i changed lots of carrier bearings on it till i got the dumb thing set right. Then I sold it and got my 1st gen.

yea Im going to take the output bearing out tomorrow and check it over.

cracked flexplate? pretty common on 1st gens, yeah....nevermind, just read yer sig :argh:

What about the springs in the clutch or at least something in thet area since it goes away when u push in the clutch just an idea.

Pressing the clutch in would reduce the drag on your rear while decelerating minimalizing the noise. And obviously you'll have added pressure on the ring gear under acceleration. Both could cause the click if there's a chipped ring/pinion tooth. I'd check into the health of the rear.

im going to eliminate that possibility today.

I plan to take the rear drive shaft out and take it for a ride in 4wd. that will limit it down to the transfer case rear bearing or something inside the case.

If the noise goes away when the drive shaft is out I am going to check over the other u joint once again and if it has any play i will replace it. at the same time I will check the slip joint better and then pull the cover on the pumpkin,

This is just getting frustrating because it is my only vehicle. I just sold my 87 150 a few weeks ago and kinda regretting it right now.

Thanks

I finally found the cause of the problem...

I popped the rear cover off and found two teeth. One was 1/2 gone and the other was almost all the way gone.

Any body have a tutorial to change a ring gear? Im sure i could figure it out but a walk through would be nice,


Thanks

Going to need a case spreader, just make sure you keep the shim pack from the left bearing cup and the right bearing cup separate. Figure out your gear ratio, get a replacement ring. New bolts too. Remove the old bolts and a few taps side to side should drop the ring right off. Heat up the new ring gear in a pan of hot water to expand it for easier installation. The ring gear bolts should be long enough to be ran in a thread or two with out seating the gear. Doing so will prevent hole misalignment. Should be able to pull the gear on the differential gradually with no issues. May even slide right over the differential being hot. Little bit of thread locker never hurt anything either.

so I have to remove the axles tubes?

right Now I have the cover off both axle shafts and drive shaft off. I removed the keepers on each side of the differential. My thoughts were it would just pop out.

please elaborate a little more. Thank you,


Kody

It should come right.

yea I looked into it a lil more. If I get a prybar on it it should come out.

I could build a case puller but many people say they've never used one and they have had good results.

I ordered a new ring and pinion with new bolts. My pinion is in good shape still i don't know should I replace it while im there? could it be worn that much to effect it if not replaced?

ring and pinion are a matched set! you dont mix them!!

that is what I figured but I was not sure. Makes sense cause the gears cout be cut at a slightly different angle.

Thanks,

Ticking type noise
 

I have a 1997 k2500 6.5 turbo diesel L65 w/220k miles. I have a similar problem. I know this is an old thread but when I search for this problem not much shows up for this truck. I ask in other forums and I get a bunch of smart a$$ answers like swap it for a Dmax or a Cummins. I know the 6.5 is a POS, but I have to fix it.
I have a ticking/clicking noise in the engine bay. I have a manual transmission. I put it in neutral. At idle you dont hear anything abnormal. But, when I accelerate it makes this ticking noise. Kinda reminds me of when the injection pump died on me or when the radiator sprung a leak. That being said i have a brand new radiator and ds4 electronic ip. Brand new lift pump, heads, head gaskets, exhaust manifolds and gaskets, valve cover and intake gaskets, new marine injectors, new gp - all torqued to spec. After doing the head job my lifters sounded like typewriters. I ran seafoam through it and did an oil change. That seemed to work. I drove it for a week then it started sounding like $hit. Like an old Ford gasser with exhaust leaks. I also have new donut gaskets on my crossover. I also noticed im not holding boost pressure like it was. Im getting boost but it wont hold steady. Engine runs great except for this noise. I have it parked. Im not driving it until i figure this out.
Also, I've relocated the pmd to the front bumper, deleted vacuum pump and installed manual wastegate, deleted ac pump, and ran straight pipe exhaust stack straight out of the hood. Any input would be appreciated. If I had the $$$$ I would swap it for a Cummins in a heartbeat
