Yet another noise.....anyone shed some light on what this noise is? Project thread from previous owner shows he replaced rear wheel bearings in November. N/S/R makes a humming sound when driving can be heard best when driving slow, jacked the car up and no excessive play or vibration, makes this squeaking sound coupled with a hum when driving. Doesn't sound anywhere near a low rumble wheel bearings tend to make. Can also hear a slight grinding when I turn the wheel in the vid as well as the squeak. Anyone help? As I said, can't really be heard when going fast as the sound isn't awful loud like a bad bearing...http://vid938.photobucket.com/albums/ad226/JoeyBoyden/Annoying%20wheel%20noise_zpsogvyoi4r.mp4

I would check the brake shoes, get the drum off and check it all out.
Personally it sounds like a dry bearing, you know know until you take it to bits and have a look.
I would first try reps king the bearings with grease and see how it goes, but you may find the bearing needs changing.

Just be sure to use the correct grease, I've seen people use CV join grease in wheel bearings, and that's a no no!
Multipurpose grease for bearings is fine

Well had both wheels off today, o/s/r moves freely wheel I turn it with no llay or noticeable vibration in the wheel and on the shock. N/s/r however which was the suspected side has blac grease all over the hub, is stiff to turn and loses it's momentum quickly when I turn it and despite having any play, there is noticeable vibration through the shock so wheel bearing it is? How do I go about taking the drum off, anything need ynvolting or just wack it with a hammer? Never done a wheel bearing before

Hmm black grease sounds to me that someone has put cv joint grease in there. If that is the case you might wanna check the good side, chances are only one bear was ever replaced, but should you find black grease on the good side remove the tapered bearings, clean then in some petrol and re grease them fully. Wipe out or wash out the black grease from the inner races that will stay fitted in the drum.
You should know the read oil/grease seal fitted to the drum can be removed by knocking the bearing out, if done carefully it can be refitted.

To get the drum off your need a large socket, I believe it's 30mm, may be 32mm, I can't fully remember, undo the centre nut and pull the drum off, it will prob require a tap around the rear outer edge to be lot it off.
If it's really had to get off then the shoe adjusted needs winding in, which can be done from a access hole in the back of the backing plate, save me writing out the procedure, just refer to the Haynes manual fella.

Replacing drum bearings are fair easy, the outer races just pull out, on the rear the oil deal is in the way, but your get a new one with new bearing.
The inner races need bearing out with a pin punch, best refur to the Haynes tbh mate, I could write it all out here but there's little point as it's covered in the Haynes.
If you have a look in the guides section there may even be a guide in there to follow with some pics.

As I alway say, if you don't feel confident you can do the job, or do it saftely, then let someone who can do it.
But it's pretty easy tbh

Here's the project thread from the previous owner. http://www.fiesta-si.com/forums/viewtop ... =5&t=25704 He said the N/S/R one was hanging on by a thread, and the N/S/R is the one making the noise so it wouldn't surprise me like you said that he only replaced one side. The weird thing is, when up to speed I can't really hear it but when slowing down or coasting it's noticeable most. Also, I've rocked the car side to side when driving and can't hear the noise really change note unlike how a wheel bearing would. I have a picture of the grease on one of the rear spacers here, left one has the grease or gue on it

Deffo don't look like bearing grease.

Sounds like bearing is shot for sure, I've had bearings which sound louder at lower speeds, and you right, rocking the car about while driving should change the note due tongue load on the bearing shifting, sometimes though you get caught out with bearings as they should, but don't always give the right signs.

I was in a mates Orion many years back, been out all night, he ranked it along this road, slowed for small round about, was doing about 20 mph coming off round about and a rear bear let go, proper let go too!
Stub axle was mullered drum fcuked the lot, and there wasn't a single sign anytime all day, right up to the point it failed, to indicate that something was wrong with the bearing..

Swap it out for sure mate, end of day peace of mind for you, you then know it's been fitted right, tightened right, greased right etc.
And also your know the whole bearings are right, I've known people just fit new inner races and leave the outer races in the drum [ERRR] they dunno how to, don't have tools to, or simply can't be arsed, to replace the outer races, and that's a big no no for sure.

Plus when you take the drum off you might find something else not right, always worth a check.


Just looked on that thread, from the picture it doesn't look like CV joint grease as it looks blueish in colour rather than grey/black, but the bearing doesn't look like it's been grease enough to me, maybe it's me, I work the grease into a bearing proper lol

Yeah gonna book it in garage for Wednesday while I'm at work I'm an apprentice myself but just want peace of mind that's it's done right gonna say to him suspected wheel bearing but I'm sure he'll know from roadrest

Fair play mate.

[JoeyBoyden]

Fair play mate.

Turned out to be wheel bearing, so got it sorted, now just to find where my oil is going! haha

[jayrs]

Glad it's sorted mate.

You kissing it or burning it?

[JoeyBoyden]

God knows mate, took plugs out yesterday and today for a check, looked a little wet on the threads but don't know if that was from the WD40 or the oil that's on top of cam cover and maybe seeped in...Cleaned sump yesterday and was wet again today with oil, done 200 miles since yesterday to test how much it's consuming not gone down too much, no smoke but occasionally get a slight smell of burning if I take it around 6.5-7k rpm. My 1.3 used to smell if I gave it a pasting but never consumed a drop...Gonna get it compression tested I think to see how healthy it is, funny thing is it still pulls like a train which gives me doubt that the rings are bad. Have a video of the exhaust from cold start up, reckon the smoke looks blue? Don't know what to do at the moment, it's losing it somewhere but I can't see the leak despite it being on sump....
