Question about 2000 Chevrolet Suburban

1 Answer

Whine in the diff - I think. :)

Hey, we have a 2000 Sub. We encountered problems with the, I think, drive shaft?? Anyway, the car stopped working properly and had a horrible whine in the (front it sounded like.) I took it to the mechanic and it was the spider gears. One of them was completely smooth. a second one wasn't so hot and the others were ok. We got them changed out and then a few days later the noise started again - mainly when you accelerated. When you took your foot off the gas, a few seconds later the noise would stop. They had not put new seals on. So plenty of fighting - and new seals. It has been in and out for over a year for them to try and get it right - still noisey and getting worse. We have now moved to another State as we are military. Is this something that is a problem with these? We had a tow package put on when we bought it, and use it if we tow anything (usually a 6x8 covered trailer - with brakes) have towed it for moving twice.
Anyway, we don't really want to spend andother $2000 plus - but figure we have no choice - any help? Also, the "leather" seat which are vinyl have ripped, where can I find replacement seats? Is it ethical for the dealers to tell you the seats are leather - when they are a leather look but are really vinyl. I said they were vinyl when we bought the truck - but my husband and his family said that if the dealer had siad they were leather then they were. My mother owned a leather shop, so i knew they weren't, and so of course they have fallen apart as vinyl does.

Anyway, I am sorry i sound frustrated - but I am! Please help - any advice would be helpful as i don't want to be dealing with this again when my husband goes to Iraq - as that is when all things car go wrong!

Hi Stephanie, Unfortunately, when you tear into a differential to replace parts like a spider gear, it is sometimes difficult to maintain the same relationship of the ring and pinion, as far as the gear backlash and wear pattern, even if you took careful measurements before disassembly. I think it is much better to replace the complete differential (inner assembly). This is what causes the whine when the gears are not wearing in the same pattern.
Having said that, I would not hesitate to buy a axle assembly from a wrecked vehicle. I don't know what happened to yours, but generally they are a pretty durable part.
The same goes for the seats, you can probably find one at a salvage yard. I think they are leather seating surface and vinyl sides.
Lastly, I would like to thank you and your husband for your sacrifices serving our country.
Hope this helps some.
If you need anything else let me know.

My mechanic has found the transmission in my 2007 Toyota corolla ascent seca Hatch(automatic) to be noisy in first gear and also to be noisy when in top gear cruising at 60-70kms. There is a whining n

planetary gears are normally straight cut spur gears and will be noisy in operation. There may be wear in the shafts that they run on and there may be needle bearing wear. Normally you will not hear the noise as you are inside the car. The whine is an indication of a mechanical problem and will be there in all gears . There is a possibility that the noise is from the diff but if you listen carefully when driving if it is there under load but changes on over run(coasting) then it will be the diff of is on and off when you hold a steady speed it will be the diff. Have an accredited transmission specialist shop give you another opinion but if it is the transmission I would not race out right away to have it replaced.

Tractor case 585xl front diff not driving. Front shaft drives but not wheels.

I am thinking that you have a broken/ stripped drive spline on a front axle. If you have reduction gears in the hubs , it may be stripped teeth on a gear. If you jack up one front wheel and turn the drive shaft that wheel should turn. IF so repeat the procedure for the other wheel and if it doesn't turn like the other side then that is the side with the problem

I have a rear whinning noise when i drive i checked diff fluid and filled and still have noise only happens when driving

It can be gear whine, bearing whine, it needs to be listened to by a tech to decide which, but generally the gears are noisy only at certain speeds that would be around 45-65 MPH and it would come and go with being on and off the throttle. Bearing noise is there all the time.

diff noises are a harmonic whine on drive (Acceleration or drive speed )or a growl on overdrive ( slowing down or coasting)
if you have a drive shaft to the rear diff it is possible that the rear shaft has not been assembled correctly and the out of phase of the joints will give indications that you describe
Take it to a drive shaft specialist shop for a diagnosis

I got a 89 2500 but the fron diff isnt working the drive shaft is turing going into the diff but the tires anrt turning i was told it some pin inside the diff

If the shaft is spinning thn theres nothing worng with the diff...(if i read right what you explained), the problem seems to be the drive shaft,probabely the splines at the front hud is gone or maybe the swivel joint has given up.

Rear Axle Bearing Replacement

That absolutely sounds like an axle (wheel) bearing. Jack up that corner of the truck and grab the top and bottom of the wheel, and shake like crazy. If you have any play whatsoever, it's a sign of a bad bearing (although you could have a bad one and not have any play - it would only mean the bearing isn't worn badly enough to cause looseness in the wheel).

You should be able to remove the axles without opening the diff up. If the axles have c-clips or snap rings on the ends inside the diff, you can usually get the axles out by dismounting them from the hubs and getting them free of all attachment except the diff, and then use a large flat-tip screwdriver as a pry bar. Use it right where the axle body mates to the diff, and lever it while you pull/yank/shake/swear at the axle, and you'll manage to pop the axle out of the diff. Sometimes it takes some time and profanity, but so far it's worked for me everytime.
