annoying noise!

[GoonerCarp]

Just had my ears syringed, hear everything now, even the nagging!!

Also noticed a rattle it 4th\5th gear. Noise stops when vehicle stops i.e. at lights etc. I did have something very similar many years ago with 2.8i Capri, that time it was thrust bearing. Could it be the same problem with my 2.7i Terrano (1998) manual? What is the best way to find out, call RAC or go to local garage or Dr Clutch, don't fancy being stitched up.

Or could it be the prop shaft.

Any advice would be much appreciated. The nagging I can just switch off, years of practice!! :lol:

From the front or back end?

Does it still rattle when you press the clutch in while still moving in 4th 5th?
What happens when you slip it into neutral while still moving?
Normally a noise from the gear box is usually a whine...
A rattle implies a higher pitch, could be something loose, resonance at certain revs etc.
Last week my mav rattled like hell, when I went underneath the bracket on the exhaust which comes off the gearbox had fractured in two.
I welded it on Saturday job fixed.. just a thought.

Thanks for the prompt responses chaps.

The noise is coming from the front end sounds like middle of the vehicle. I've checked the prop shaft that seems solid with no un-natural play in it.

I haven't done the neutral thing, but have depressed the clutch in 4th & 5th the noise is still there. if anything it's getting more consistant and sounds more of a rattle rather than a whine.

The more I think about it, I think something has snapped possibly a bracket. Will have a closer look underneath after work tomorrow.

If it is a snapped bracket and say it is the one you are referring to Rustic, is welding the best thing to do or replace the bracket. I can't weld, I wished I could. Is this a common failure?

Another thing is the performance of the vehicle is not effected, if it was a bearing or gearbox problem I would expect a lack of performance.

I'm beginning to feel I've jumped to the wrong conclusion, rather than think it out

Thanks gain for your advice, I will keep you posted.

Just a thought and probably wrong but is it a front hub that has stuck in the locked or partly locked posistion?

how would I know Jim? - if tuck, wht is procedure to free it? is it to do with the 4 wheel drive? No indication that 4 wheel drive is engaged i.e no dash light on! Or is it a wheel off job?

Cheers

the reason i asked if the noise was rfom the front or backend was because their are 4 drop links 2 front and 2 rear these can rattle when worn normaly during motion and louder over uneven road surfaces if very bad they could rattel from engine vibration and easy to check out :?: :?: :idea: :idea:

 

[GoonerCarp]

Fingers crossed that the weather will remain dry, so I can get underneath after work tonight.

At least I have a few things to look out for.

Really appreciate all your suggestions and advice, goes to show that it was a tenner well spent.

Thanks again. :smile:

we get a rattle from the exhuast with nothing broken. can seem like car is labouring slightly so use a lower gear and more throttle. of course slowing down its there. suprised only getting in 4th or 5th though.

If the hubs or hub is stuck in the engaged posisition the light on the dash wouldn't come on, that only comes on when the lever is in the 4wd posistion. Good news is you don't have to remove wheels to check hubs. There is a couple of sections in the download page regarding these hubs and also several previous threads regarding them. Like I said it is only a suggestion. Mine stuck twice and it made a clicking noise which got loud at one point.

If you look at my bracket that I welded, you would say that I couldn't weld either.. :lol: :lol: :lol: Although my Mig welder works better than a stick welder..
I will never use the welder for anything structural, but it's handy when the exhaust falls off or an exhaust bracket breaks.
Perfect for wheel barrows and gate post hinges and the like...

Had a quick check last night, wonderful stuff pouring with rain, but at least theres enough height to get under to keep relatively dry! Never had that luxury with the lowered Probe, just enough room to get the jack under.

Anyway, couldn't see anything broken, but the u-bolt on exhaust front end along side gearbox is slightly loose, not sure if loose enough to generate the annoying noise! but will get replacement u-bolt and see where I go from there. I know something as simple as that could possibly be the problem :?

Next question what size u-bolt is it a 2 1/2inch?

Thanks Jim for the advice on the front hub, I will print off and have a read during a quiet 5 mins at work.

So thats why you go to work -killingme- -nerd- -rotfl-

Very funny, but have you seen the price of colour ink cartridges? :smile:
Just call it the perk of the job.

For some reason our IT Dept linked me to a printer that does posters, so I could print out the hub guide on glossy paper that is 6ft x 5ft!! :lol: :lol: Very tempting :smile:

Quiet moment, printing done, on normal paper of course, but in colour :smile:

If the exhaust u bolt is the same one as mine it kept coming loose and in the end I stuck an extra pair of nuts on it to lock it up solid.

When I had the front exhaust changed, they replaced the U bracket, and guess what the bracket rattled, so as per Jim Ts post, I fitted double lock nuts. Then 12 months later the bracked broke.

Conclusion, when the U bolt starts to come loose, the Exhaust bracket has probably started to fracture. While you are under there with a new U bolt, just undo the bracket, 2 bolts that screw into fixed nuts.
Worth checking while you can.

 

[GoonerCarp]

The bracket looks ok, I think it is the u-bolt, I will replace that tomorrow with extra nuts. May go to dealer or exhaust centre for the bracket and keep it handy.

Thanks again chaps

Having welded my exhaust bracket and driven the car for a week it has started to squeak a little again..
I checked the welded bracket and that's ok :smile:

What I have done now is I flattened a short length of 15mm copper pipe approx 70/80 mm long, drilled 2 clearance holes 10mm at the ends to line up with the threads of the "U" bolt and slotted the holes to the ends to allow movement.
I sandwiched this at the top between the bracket and the exhaust, and then fitted the "U" bolt back (2 nuts per thread). The flat copper pipe compressed behind the bracket and pipe and took out the clearance that was causing the squeak.
It's quiet again now... but for how long? 8O
Thank goodness we can do these types of job without having to jack the vehicle up. :smile: :smile:

Hi Rustic, notice that you have Rossini discs, what do you think of them, I fitted them all round on the Probe, very impressed considering how ell priced they are!

Right, back to thread, Saturday morning had a proper look, found bracket loose, when checking all other areas found exhaust knackered, so down to local exhaust place said think exhaust in section needs replacing and whilst at it can they confirm if that is cause of rattle. They checked, said it does appear to be the cause, so centre and rear box replaced new brackets fitted and rubbers etc. marvellous I thought until i gets down the road and the rattle is still there :?

Still the same symptons, running moving seems all the time now, rattle, stop vehicle rattle stops. Have tried going into nuetral when moving, rattle still there, in nuetral with clutch depressed (bit like i'm getting) rattle still there.

So at a loss now to problem, only thing is to take it to dr clutch or some other establishment, but I dont think it's the thrust bearing, if I recall this will rattle like anything and vibrate. There is no loss in performance of the car!!!

Haven't had a chane to check the hubs yet. I printed the downloads regarding the hubs, so will give it a go at the weekend. if one or more is knacked what cost am I looking at? Please be gentle with me!!

Cheers all
