New gearbox whines like a pom.

Post by **topdown** » Sat Mar 01, 2008 11:33 pm

I just put a new reco gearbox in my Sierra and it is really whiney.
I figured it might just be because it's new and needs to wear in but it is quite loud.

Has anyone else replaced their gearbox lately and had a similar noise?

I also replaced the pilot bearing in the flywheel, the clutch and the thrust bearing. Whole lot is new.

did you add oil?

Post by **topdown** » Sun Mar 02, 2008 6:01 pm

Yes I put oil in it before I started it.
I may be a zook driver but I'm not completely stupid.

I'd be taking it straight to the mob that reco'd it before it blows up and they find a way to void your warranty.

Yeah I think I will. I just wanted to see if anyone else had a similar experience with a reco'd box before I do. It all runs perfectly and feels great it just whines.

It doesn't do it when the clutch pedal is in so i'm pretty sure it isn't the clutch.

Post by **bazooked** » Mon Mar 03, 2008 10:49 pm

could be the throw out bearing on the clutch, sounds like it might be adjusted wrong or not fitted correctly.

Post by **oozuk** » Mon Mar 03, 2008 10:54 pm

a reco'd box should be quiet straight away

Post by **topdown** » Tue Mar 04, 2008 8:40 am

Thanks guys I'm going to check the thrust bearing out first as it seems to disappear slowly as I push the clutch pedal in. It also doesn't do it in 4th or 5th gear for some reason or on deceleration only on acceleration.
Really weird?? I don't want to take the box back without checking all avenues first. If it's not the thrust bearing I'm pulling it out and taking it back for a refund.
How bloody annoying though, there goes another Saturday eh?

Take the whole vehicle back as it is now so they can hear it. Still sounds like a gearbox bearing to me.

Post by **topdown** » Tue Mar 04, 2008 8:52 am

Yeah good point. Pretty hard to prove it's faulty if you can't hear it running.
I'll take it in today.

Post by **gumtree** » Tue Mar 04, 2008 7:23 pm

its the bearings inside the gearbox, gearbox bearing, had similar prob but it was coz it was a old wornout gearbox.

who did the reco? i just want to know who to avoid. its obviously not recond, whatever they say... unbelievable, isnt it...

Post by **topdown** » Wed Mar 05, 2008 8:34 am

Got it from Tempe Tokyo spares in Sydney.
It was looking a bit suss when I got it. The thrust bearing was worn out and one of the locater studs was missing. Looks like they just spray painted a used box and tried to palm it off as a reco. I'm taking it down there tomorrow morning to kick some ass. Wanted to do it today but too busy.

dodgy bastards.

i hope they will at least give your money back but should also pay u extra for wasting your time taking the gearbox in and out and stuffing around with them.

u can sort of tell next time if a gearbox is noisy by spinning the centre shaft (where the throwout bearing goes) with your fingers and if it feels smooth and quiet, its prob good. i bet if u spin this one or your old one it wont be perfectly smooth.

Yeah I'm really pissed off about it. They are going to have one angry person down there tomorrow. I'll definately be testing the next one out a bit more before I install it. My buddy is going to give me a hand to pull it out on Saturday.
It'll be much faster process this time round as I know exactly what needs to come out first and I won't have to work on any tight bolts for 1/2 an hour etc.

Now I need to remember where I put the receipt

Took the car in this morning. Pleasant surprise the guy was really good about it.

Apologised profusely and explained that they didn't reco the boxes and got it from an external mob.

Didn't muck me about and is getting me a new box to pick up Saturday when I drop the dud one back.

But it was the box making the noise. I took it for a drive last night for a final check and remembered that the 4th and 5th gear is straight through
and they where the only gears it didn't whine in.
So it definately wasn't the clutch or front bearing. Something else is amiss in there.

Thought so, lucky

So what you are saying is it was a Dulux rebuild.

Sounds like an input shaft bearing?

Didn't accuse them of anything as I wanted it sorted.
He was good about it so no need to enflame the situation.

I think he will probably be having a word with his reco'd box supplier though.

I'm glad it was the box and not the clutch. The box is a pretty easy in and out job but the clutch is a bit more fiddly. Wouldn't want to have to pull it all out again.

All fixed now.
Got the new box in on Saturday, heaps faster second time around.
Now it's so quiet I can hear how worn my wheel bearings are:)

Anyone done their wheel bearings lately?
Any tips or special tools I'll need?

Post by **mrw82** » Mon Mar 10, 2008 5:28 pm

i'll be doing my front wheel bearings next weekend
dont know if theres any special tools required (guess i'll find out soon) but i've got some prices for you:

price from Ripco =$90.00 per side
price from suzisport =$80.00 per side
price from onlineautoparts.com.au =$99.00 for pair.
(onlineautoparts also sell through ebay)

pays to shop around.

you need a 50 mm hub socket. did mine the other week and had to get a socket up from vic.

Post by **gumtree** » Mon Mar 10, 2008 8:10 pm

coventry auto are about $56 a side from memory. try supercheap as well, they are cheap.

thats good to know, wasn't sure what size i'd need, i'll see if i can get ahold of one from work

searching for wheel bearings will give a run down on the tools and bits required.. torque wrench, 50mm hub socket, might want to do king pins while the bearings are out.. saves pulling it all apart again in 6 months time..

x2 If you can afford it, it is worth doing king pin bearings and all the seals while you have it apart. And even wheel bearings.... if they need it. A thorough wash out and regreasing of the cv's also. The cv's and swivel hibs take black Moly grease. The wheel bearings take red or blue standard wheel bearing grease.
