mild freak out need some input

samibattlemaiden · 10-18-09, 05:45 PM

so i ran to the store to get some stuff for dinner and i noticed a strange clicking noise on the way home? not sure if it was there on the way there as i had my music up. pulled over to see if i could figure it out. only happens when truck is moving. seems to be coming from drivers side front wheel area? checked axle for oil level thinking it might be empty. seemed a bit low (not enough to be causing any problems i wouldnt think) so i topped off. thats all i could come up with?

i have no idea what it is but i need to figure it out stat. i drive to and from sac every day for school and shes my only vehicle so.....

wouldnt think any of them would be the cause but only things done different lately are i changed the oil maybe 600 miles ago, got new tires like 500 miles ago and like a bonehead left my lights on earlier today and killed my batt?

help me

Be a little more specific, does it sound like its coming from the engine, steering components, ...? I have a clicking coming from the front drivers side wheel area of my vehicle. I got under there and checked all the steering components for play and there was a small rod that was moving around because the bushing had rotted away that was making the noise. Try to center in on where the nosie is coming from.

If some noise had developed from the oil being low I think you would notice a lot more than just a clicking noise, something would go really wrong IMO.

Good luck and let us know.

samibattlemaiden · 10-18-09, 06:01 PM

best i can tell it is comming from the drivers front wheel area. my first thought was that the rubber gasket on the hood was hitting my fan (po removed the fan shroud and i have not yet put on the replacement i got and the rubber hood seal gasket hangs down on the driver side cause 2 or 3 of the little plastic screw things rotted out) but it isn't that i opened the hood and no polished marks on the rubber, also i gave it gas via the throttle linkage and nothing.

sound becomes audible about 1500 rpms and gets louder the higher the rpms go. nothing at a stop and nothing revving in neutral.
im gunna go take a lap around the block and see if i cant come up with a better description of the sound

specialk396 · 10-18-09, 06:04 PM

have you checked your hubs? Is if different if they are locked(or unlocked)?

samibattlemaiden · 10-18-09, 06:11 PM

i have not and yes i will. that was my next thought. does it sound like my birf blew? and if so why i have not had her in 4wd in a long time? brobly more then a year

tonyota · 10-18-09, 07:16 PM

Sounds like a hub to me....Lock out spring or retainer out of position....pull the outter cover off the lock out...drive without it in place around the block & see if it stops

krookedpandas · 10-18-09, 08:19 PM

Wobble your tire and feel for free play.

samibattlemaiden · 10-18-09, 08:28 PM

well never fails im out there trying to figure it out and some one i havn't seen in a long while stops by so work time got cut into, ill hafta check those after school tommoro but, im kinda thinken it might be my tranny.

makes me think this cause it gets louder with rpms and locking or unlocking hubs made no differance. also once the tranny possibility occured to me it reminded me that last week i heard a metalic ping sound when letting off the clutch pulling away from the atm and a few other places where i had a solid wall directly next to me to give me a good sound bounce back.

im hoping im wrong. if it's the axle no biggy as im gunna be swapping them out for 62 axles in the near future but if it's the tranny then my 2fe will probly be put on the back burner for a while.

samibattlemaiden · 10-19-09, 07:08 AM

Does that seem right or am I over thinking?

knowaste · 10-19-09, 07:24 AM

Based on your symptom of hearing things as you move next to a wall...I have got a throw-out bearing just a hair off line and will get a click when engaging and then a light noise, reflecting rpm, only under load. So no noise at a standstill...only under load...out of gear coasting, no noise. The control arm on the clutch can be a bugger and my bet is your throwout is off?

lehiguy · 10-19-09, 09:27 AM

The two most likely causes are brake pads clacking as the rotor's runout makes them move a little with each rotation of the wheel. This is usually only an issue if you don't have the proper anti-rattle hardware in place (the funky springs that go between the pads.) Next would be the birfield but that would only be evident if its turning, meaning your hub(s) would have to be locked or you T-case is in four-high.

samibattlemaiden · 10-19-09, 11:54 AM

Havnt tried rolling out of gear and have not checked breaks yet. I'll check those if I don't feel like death still when I get home.

CardinalFJ60 · 10-19-09, 11:59 AM

If you can't find anything mechanical wrong....maybe a rock in the tire tread?

OR....maybe the little plastic thingie where the wiper arm goes into the body? mine is loose and rattles a little bit when moving.

rchalmers3 · 10-19-09, 04:24 PM

Yo Sami,

Are you familiar with pre-detonation, also known as ping?

Rick

samibattlemaiden · 10-19-09, 06:54 PM

cardinal i would love for it to be that simple,
rchalmers3 yeah, does detonation only happen under load? cause i can rev the bejebus out of it and it does not happen. also detonation is heat related correct? she does not have to be hot to do it.

i really wanna figure this out and will try all above suggestions that i have not tried yet but, unfortunately i have this fantastic flue thats goin around and the wife has me on lock down to the bed tell im better or it stops raining which ever comes first. or tommoro when i get home while shes still at work.

samibattlemaiden · 10-19-09, 07:14 PM

so i had another thing occure to me sence im dreading that its the tranny. lately i have noticed it is increasingly hard to get into secound gear when down shifting to slow down. should i have seen that as an indication of catastropy to come?

samibattlemaiden · 10-21-09, 08:44 PM

so i had a few min to try to figure this out again this evening, lifted front driver corner spun tire no horrible sound, tried the same in the back with same results, though i only have the bottle jack currently as my stands are locked in my buddys garage...

no play in the tire when lifted, is it possible im just not able to spin them fast enough to cause noise?

went for a lap around the block. sound gets louder and faster the more i get into the skinny pedal. forgot to see if it continues if i put the clutch in and just let it roll but don't think it would.

does detination only happen when under load? i reved it to about 3k and it does not happen....

any other thoughts?

RockDoc · 10-21-09, 09:02 PM

Exhaust leak? Do you notice it getting worse when turning? That could be a motor mount... would be worse in low range climbing a steep incline. Any evidence of the fan rubbing the shroud?

samibattlemaiden · 10-22-09, 04:57 AM

no shroud to rub on. and i would be able to see the engine lurch when goosing the throttle linkage no?

Maybe not when there is no torque load through the drivetrain, but I suppose you would see the shifter and transfer levers move significantly with load when driving. But if there's no shroud, then that wouldn't be the source of the sound.

Trollhole · 10-22-09, 07:42 AM

Rock or screw in the tread?

samibattlemaiden · 10-22-09, 09:39 AM

Nope as nice as that would be I think it will be more labor intensive than that

samibattlemaiden · 10-22-09, 09:39 PM

is there a way to post a sound file or do any of you tranny sound experts wanna let me email the recording i got with my phone to you for further diagnosis?

so for sure no sound while rolling with clutch in even if i depress clutch and rev engine while rolling, straight or turning make no difference. gotta be tranny right?

Usually, yes- will ping under load or when "bogged down" in a gear.

Mace · 10-23-09, 10:46 AM

Is it engine driven or speed driven? Meaning, the noise is faster at 60 mph than at 45 mph. (assuming the same engine RPM)

I bet you are getting predetonation.

samibattlemaiden · 10-23-09, 11:40 AM

Seems rpm driven over speed but I have avoided high speed sence I noticed the sound

OlympiaFJ60 · 10-23-09, 09:06 PM

"revving" and "under load" are two different things. To check pre-detonation, going 25-30 in 4th gear, press the gas peddle down all the way. This is "under load" and could be timing related. you can also get detonation from carbon build up on the valves.

I was wondering too if it was vehicle speed or engine speed related, clutch in or out. If the clutch is wearing out (getting hard to put into gear) you can also get throw out bearing noise. My 5speed is often hard to get into 2nd, but I think that's more a bad syncro and wouldn't contribute to a rotational noise. Have you tried driving without the front drive shaft? Just another thought.

samibattlemaiden · 10-23-09, 10:15 PM

olympia no i have not but will do a lap tommoro minus front shaft,

so from what i do understand of pre-ignition/detonation it should be atleast temporarily remedied/lessened by using higher ocataine fuel and adjusting timming? also i read that if the engine is not breathing well enough it can contribute?

so change air filter, premium gas and playing with the timming should help?

hank14 · 10-24-09, 08:10 AM

You really need to figure out if this is engine noise (pinging) or drivetrain noise before trying to adjust everything. Try the driveshaft removal first. Then report back.

samibattlemaiden · 10-24-09, 08:21 AM

hank thanks I know one bandaid at a time so i know which one is the actual bandaid, im just trying to figure out what ill be doing today in which order

driveshaft-ectomy makes no differance
