Whining on

Yes it is a 4wd and i wondered if it was the diff what do you think? oh and the tyres are like new!

I found it quite hard to work out from where the noise was coming. The garage put it on a ramp with a rolling road type thing, so they could pinpoint the source.

You might need to do this to track down your problem.

I once suffered from a nasty noise, which changed at different speeds. My problem was found to be the tyres, even though they look fairly new they were out of shape (seemed to happen suddenly)

See picture in belows thread:-

The rear differential was excessively worn. This was not unexpected as the (different) garage that repaired the viscous coupler when it failed said they needed to adjust the "pre-load" on the rear diff because it was making a noise. (The front diff failed completely and was replaced with one from a breakers yard.) The adjusted rear diff lasted just over a year.

Given the hassle caused by the viscous coupler failing, and the fact that they do seem to be unreliable in general (not just on Bongo's) I would not have a car with one again!

I think if I was you I'd be disconnecting the front propshaft and just running 2WD Tony................

I have thought of this, but one of the key reasons for getting a Bongo was because it was 4WD. It wouldn't have helped this time round anyway as it was the rear diff.

I need to think about this for a while.

By the way, I got the Bongo back this morning, and it seems to be running OK for the moment. (And my back has recovered - as much as it ever does!)

Hi guys here we go with the next chapter i have allegedy had this noise fix that has cost me £140 (they originally wanted double that) after a bit of haggling anyhow I was told that the Bonga had been caught underneath and subsequently damaged a bracket wich holds the front diff in place allowing the diff to break a seal and leak oil I was assured that a new Bracket and a bit of tinkering it should be ok oh and a top up of diff oil would do the trick so imagine my surprise to drive home the 40 miles with a CONSTANT whinning noise STILL!! so my question or questions is 1 where do i stand having paid for a repair that was not required and secondly do you guys think it is possible that it could be a wheel bearing playing up, the reason i say that is that the problem is definatly motion related ie the faster the louder what do you think and is there anyway of checking for bearing wear and tear

If your wheel bearings are worn enough to be noisy, you should be able to rock the wheel from the top to bottom when it is jacked up.

Chris.

To check for wheel bearing wear:

1, Park the van somewhere flat with the handbrake off.
2, Work your way around each wheel, grabbing it at the top of the tyre and vigourously pushing in and out. If any of the bearings are shot, you should feel free-play.
3, Drive the vehicle and try cornering hard in both directions. If the sound changes or dissapears then this will give you a clue as to which side is gone. Eg. turn left and sound gets worse, the RH bearing.

If you do feel free play, be sure that it is in the bearing and not the swivel joint or any of the other suspension joints.

Hope this helps and good luck.

Sorry Franco, you put it much better than me and you obviously type a lot quicker too!

Ah, fingers. I need to get away from using my elbows then!

Thanks guys I ll give that a try. What about the paying for repair that was not required???? Chris.
