HUMMING NOISE FROM THE REAR HELP.

Hi Members.

can you advise, i took the stag for a good drive today. for 20miles or so. and noticed a sound from the rear, like a humming noise from maybe the rear right or rear left. do you think this might be a wheel bearing???!!!!!!

Please HELP

ps: My Car Is A Triumph Stag M2 1973

Yeah, a continuous humming noise is often a worn wheel bearing. Generally, the noise will be worse when going around bends. If a bearing on the passenger side is gone it will make more noise on right hand bends. And vice versa if one is gone on the drivers side. Also if it's a bearing it will probably make noise even if the car is coasting with the drive disengaged. If this isn't the case then the sound could be coming from the engine or transmission.

LOL, great thread title

Thanks Brian.
i just took it for a test drive,and it does make more noise on right hand bends' And vice versa.and it also make's noise even if the car is coasting with the drive disengaged. so it seems like your correct. what now??
is it a easy job to refit new rear bearings to the REAR?!!! and how much will the parts be. or would it be better if i take the Stag to a garage to do the job.......ADs

Can't really answer those Qs as I'm not familiar wih Stags or older RWD cars. But wheel bearings are generally not a big job. I would hazard a guess at around 1 hours labour to replace 1 bearing and maybe 40-50 quid for the bearing itself.

If the noise is a steady drone/hum it is likely to be a bearing. If it's a "lumpier" sound that would be less conclusive.

Also check for play and listen for roughness in the bearings by jacking the car up in neutral and rocking/spinning the wheel by hand. You might not find anything from this as the bearing that's making the noise when driving may not have deteriorated too much.

hi, its a fairly easy job to do. but if unsure take it to a garage. inner & outer bearings guess about 50 euro, try james paddocks in uk they normally have best prices and service. mounttown motors in dublin know Stag inside out. if you want there number private message me.
Also be aware the diff could also whin!!! but from what youve stated its more likely wheel bearing.
try jacking her up and rotate the wheels you should her humming or put one hand at top of tyre and one at bottom there should not be any movement both would tell you wheel bearing.

Thanks Members. does anyone know a website on how to do this job in detail with pictures???
ADs
PS: Or is there anyone who wants to do the job for me. i will pay the right price

adam01

Yes the noise is a steady drone/hum it is likely to be a bearing. If it's a "lumpier"
I'v checked for play and listen for roughness in the bearings by jacking the car up in neutral and rocking/spinning the wheel by hand.

And yes big time play in the hub , and when i had a listen for roughness in the bearing"YES" i can hear that very well.i,v been told that it is not a easy job to do. and that the rear rightside hub has to come out. as the bearings are conpressed in by a factory. i have to take my Stag in the Stag garage.
as they will take the hub wright out and exchange for another with new inner & outer bearing in place. will cost around €260 ouch.

But Yes it is with out any doubt, it's the bearing?? what do you think.....ads

This doesn't sound right. It is true to say that wheel bearings can need a lot of force to get into and out of a hub. This is generally done using a press and is a well known procedure, a garage should have a press or if not be be able to bring the hub to a place that has a press.

I have heard of people using a bench vice and a suitable sized socket to press a bearing into a hub. This may work for some cars but not others. A press is the proper way to do it though.

Sorry to hear that, Adam.

Contact Doug or Jeff at Mounttown Motors in Deansgrange on Monday, they treated that car well when they worked on it for me. Since they know Stags, they will probably know the best/quickest/cheapest method for replacing bearings anyway.

Here's the number for Mounttown: 01-280-6530

Doug himself did a big service on the car before I brought it to you, so he will no doubt remember it.

They're a good crowd, Mounttown.

adam01

Thanks guys.
Frank i will give him a call 1st THING ON monday, and see whats what. its just wear and tear, these things happen. as you know me .thingshave to be in A1 condition.
Today wasn't a good start, as the Stag did not want to turnover what so ever. i thought is was the petrolpump? but after looking at 10 different things' I foundthe problem. the petrolfilter in the engine dept was full of s*** so i put a new one on. and bobs your uncle, she started up. yah
What should the tick over be?? as its at around 8k refs at the moment when at normal temp.
Cheers....................ADs

ALL OF WHAT YOU STATE IS CORRECT. BUT YOU CAN DO IT ON A BENCH PRESS TOO. BUT BE CARFULL IF NOT SURE AS THIS CAN DAMAGE THE UNIT AND REMEMBER TO GET A RECON UNIT YOU WILL NEED AN EXCHANGE UNIT, THE SURCHANGE CAN BE HIGH IF DAMAGED.
BEST AND CHEAPEST IS TO GET AN EXCHANGE UNIT. AS IF A GARAGE WAS TO DO IT THE TIME IS HIGH AS YOU HAVE TO STRIP THE WHOLE SHAFT AND TIME GETTING NEW BEARINGS IN. THE HOURS MOUNT QUICK AND LABOUR HOURLY RATE LANDS A BIG BILL. SO FOR AROUND €260 YOU WILL SAVE AND GET THE CAR BACK QUICK.
DO YOU GET HER STARTED TODAY?

HI MANUAL MODEL AROUND 850 - 900 RPM MINE DOES IDLE QUITE HAPPY AROUND 750 -800 RPM AND SHE IS 73 MK2

Ads - the starting problem. God knows why, but it seems to be a "known" problem with Stags that they will once in a while just not turn over - as if the starter is jammed, or the battery is flat. But if you reset the keyswitch and try again, hey presto.

Mine did that to me today, that's how I know about it. Looked it up on Triumph Torque (the UK site) and saw the description there. People say to ignore it unless it keeps happening, in which case it's probably a starter or solenoid problem.

I know Dublin's a bit of a trip for you from Roscommon, but it's worth it if you need stuff doing on your car by Mounttown. Is the bearing noise really that bad ? I'd tend to live with it, assuming it's not a diff problem, for a while until you're over in Dublin anyway at some stage

HI FRANKSM,
VERY TRUE ABOUT STARTING, IT CAN BE EATHER OF WHAT YOU MENTIONED ABOVE BUT CHECK YOUR EARTH LEAD FROM THE BATTERY THAT THEY ARE TIGHT AND THE ONE ON THE INNER WING THAT LOOPS TO THE BRACKET AT THE POWERSTEERING UNIT. IF THEY ARE EVEN THE SLIGHTEST BIT LOSE CAN CAUSE THAT PROBLEM. TURN THE KEY DEAD.
CHEERS

adam01

Frank.
i got it wrong it turns over , what i should of said, it did not fire up . seem like a the pump was not working. but like i said i change the filter and she started. but still with a strugle. yestoday as i was driving the Stag. it seemed a little slugglish??!! and then this morning it did not want to start. ......ads

ps: i hope i make sence

franksm

Thanks Jack - there's one thing I can be very sure of, since I replaced the alternator on Adam'scar - the earth lead from the battery (or is it the body) to the alternator bracket is indeed in place and strong. I'm not altogether sure if it's tight at the battery, that'd be something to check.

franksm

Ah.. okay. Was the engine cold (ie. this was the first "start" of the day) ?

If so, check your choke cables - I know you had the dashboard out, so you need to make sure that the choke-pull is opening up *both* carbs enough. Pull the cable while watching the carb linkages and you'll see what's what - then go to the carbs and do it with your hands - if you can move the choke more with your hands than with the choke cable, then the cable isn't setup properly somewhere

Spot On Frank.
1st thing in the morning when the Stag was COLD. i did look at the choke cable, and it seems ok?? do you think it just might be condensation?? when you start up in cold mornings, do you just use the choke and not put your foot on the gas.

The Stag needs a bit of both:

choke out all the way, and accelerator in 1/4

(although I wonder if that points to the choke's "fast idle speed" setting being wrong, as some carburretor automatically increase the throttle when the choke is activated - not sure if the Stag's does that)

I don't think condensation is the problem - there's new distributor cap, plugs, leads etc on your car. Maybe squirt WD40 on the distributor cap and see if that helps.

my pennys worth again,
on a Stag use the choke only not the gas, if she has not started by the third or so turn over just push on the gas a little not much and she should fire straight off.
the carbs can flood very easy. If this happens put your foot on the gas to the floor, once started let off to about 1/3rd. DO NOT OVER REV THE MOTOR.
Franks point on the choke cables very valid check they are opening fine.
Stag's on the norm will start without gas only choke.
