Got a problem now that it's cold out (1 Viewer)

[REDDER1]

I get a weird noise when i start only in the cold also. Best thing i can describe it as ..
it seems that the starter keeps trying to start the engine even after it started..like a whine for a bout 2-3 seconds after startup..then goes away. This isnt an inssue in the summer or when the engine is hot.

Rick. you repack every 30K? I need to figure out how to do that. I can 99.9% gurantee that the stoopid PO of mi rig NEVER had that done. Considering i pulled off the origional shocks, steering stablizer @ 96K i doubt they made an effort to go beyond the regular oil, filter, air filter, tranny fluid maint. schedule.

I've gotten that same first start grind a few times now. After the first time I rebuilt the starter but it has happened a few times since.

As of now my battle plan is to take another drive in the morning to check for the noise with the ABS fuse out. Then clean and grease the front bearings. I'll reinstall the fuse for the ABS and then see what happens.

Be sure you give it long enough to rule out the ABS. By that, I mean it's a very high probability, so repacking the bearings before running until either 1) the noise is made, or 2) the noise is clearly gone - would be a waste. Said another way, wait until you've heard the noise w/o the ABS system active.

I understand your thinking Mike however this being a DD for me means that with a phone call I could be driving to up state NY or down the PA Monday. Ed mentioned his problem when hitting a bump which I have also noticed. I know this also figures into the ABS but I can't take the chance that it is the bearings and have a full blown failure 300 miles from home. Hopefully this mornings drive prior to break down will reveil something.

Well just got in from the spousal avoidance center. Beside repacking the bearings I replaced the rotors and put on 100 series pads.

Everything looked fine. However the shop that did the axle service and gears didn't clean the hubs out of the old grease. Looked like the repacked the bearings and moved on. Thought that this was important unless you were sure of the type of grease used prior. Remember something about different base stocks not working well together. Anyway they had mixed some and the amount of grease that was in the bearings seemed on the light side.

It has warmed up here and I wouldn't expect it to happen anyway, so the ABS fuse is installed and I'll let everyone know what comes of it.

"spousal avoidance center"


Garage?

Well it's NOT the bearings. Went shopping this evening with my 2 kids and the noise happened 3 times in a mile and a half. The final one was with extreme prejudice as it just went on and on. I was able to reconfirm that the motor rpms have nop influence, also during breaking at a normal speed has no effect, however it tails off as the speed of the vehicle slows and drops out at around 10 mph. The last one was right up til I stopped the truck, I then removed the ABS fuse and the problem didn't happen again for the rest of the night. Today it finally dropped back down into the teens so with the fuse out tomorrow morning should provide some info hopefully.

Rick,
When you did the rotors did you remove and clean the ABS sensors? Sometimes they build up with metal shavings (they're big magnets) and their signal gets fouled up.

If I get this one right, I'm still at 100% for remote diagnosing. It's the ABS system.

I read through the ABS part of the FSM. Not much on theory just checks. I have a derive today and if the noise is gone all day then I'll start by cleaning the sensors. Now in the rears I can clean the sensors and clock ring by taking off the rotors. What about the fronts? That ring is on the birf right :'(.

I'm trying to take things in steps so I can identify exactly what is going on and what the solution is. Might help someone else out.

 

[landtank]

it only took 300 feet. it's not the abs system.

Just beyond the crest of that first hill , at the stop sign then ?

Boy is Doug gonna be pissed ! :-X

Maybe you could hold a good digital camera out the window , and get an mpeg of it for the audio ... then host it somewhere for us to listen to . Hahah ... not asking too much , eh ? Sorry .

Tyler - interested to see what the hell this is ... [glow=yellow,2000,3000] [/glow]

Rick-

I have the exact same prob with my 96. Started about 7 months ago. Comes and goes, some days it would never do it. Mine did it when it was warm too. Just another project I have to start working on and your research will help guide me!

Thanks again.
Mark

Unbelievable! I've had that same problem for 3 Minnesota winters. The first time I heard the noise, it nearly sent me into the ditch. Very LOUD!
Rick, I appreciate you going step-by-step in diagnosing the source of the noise. I took mine to a Toyota dealership (still under warranty) and after several "test drives", they had zero clue as to the source of the noise. I have not had it happen yet this winter, but it definitely vibrated the floor board by the gas pedal and it is negatively correlated to the temperature outside. Colder the temp, the more noise I get.

Do you notice this noise/vibration on sharp turns while accelerating? Not on the little old lady going to church acceleration or putting the pedal to the metal but something in between the two extremes.

 

[cruiserdan]

Rick,

The Wulf may be on to something. Yes, the front ring is on the birf "bell" but you can easily pop the sensor out of the top of the knuckle and see if ther is any metal stuck to it that may be giving it fits.

Sounds Like I've been selected to Champion the cause :'(.

Tyler, already thought of that , and I won't have to have the window open to record it .

Dan, this morning I had the 60a fuse out of the ABS circuit. Got to beleive that would have disabled everything and ruled it out as a cause.

Everyone else, damn near stained my shorts the first time it happened. It does seem to be weather related. I've noticed it worse when there is a large drop in temp to below zero. I'm starting to look at the EVAP system because my 4Runner had buzzing noises at the other end of the thermometer which was a hose. Of course that solution was provided by Toyota in a TSB. Anyone have access to those things on the board?

Does anyone who has had this have a stock vehicle? I waited about 3 weeks before modifying mine so I'd like to rule any of that out.

I should have a sound file tomorrow. Just won't know what to do with it, any ideas? Even though I'll record it on my camera I can strip out the video and compress to a MP3.

 

[Tank]

Mine is stock to the bone.....

Jeff-I have the same deal with my floorboard...
PPC-Not on turns and slow accelerating, jamming the gas only makes the noise go faster = -)...........Had a friend look at it but the dam thing wouldn't do it when he drove it!!!!!!!!!

 

[landtank]

Just realised....we're all 96's...what the hell could that mean?

 

[landandsea]

Rick,

I know that you repacked the wheel bearings, but i have to jump back in here again.

The noise I had sounded like a very low bass note on a wind instrument and while it was definitely coming from the front PS corner, I could feel a vibration in the floorboard on the DS. I decribed it before like a goose honking. It was the opposite of the high pitched squeeking of bad bearings of past vehicles.

The first time it happened it sounded so bad that I had visions of thousands of dollars fleeing my wallet.

Too many similarities to ignore. Mine's a '96 also.

The inner wheel bearing was not mangled or missing little balls or even visibly bad to my eye. Yet the tech said the race was bad and now the noise is gone.

I'm not trying to talk you into anything, but of all the 96's reporting the noise, mine is the only with the problem solved and that was by replacing wheel bearings (for which I take no diagnostic credit at all).

Good luck to all,

Ed
