Bearing noise

[Ian F]

I have an awfully noisy bearing somewhere on the Stag but other than replacing each one until I find it - what else can I do?

Replaced both front bearings with new discs etc., 18 months ago, and the rear bearings were replaced, alongwith recon 3.45 diff (inc new nose bearing) 6 mths before that.

Whining/grating sounded at the front and worse on left hand bends so replaced front offside bearing - it didn't look to good butlittle if any difference, - noise still there. Sound does not appear to be coming from the rear bearings - so I am now wondering whether it is from the front diff extension bearing and noisy along the propshaft?

Anyone got any ideas - or a known, good diff nose extension that I can try? I don't fancy replacing the rear hubs/bearings to find it does not cure it? Any ideas please?

Have you checked the viscous coupling? When the bearing gets loose it makes a horrible noise as if something really drastic has gone wrong! Grab the fan with the engine off :shock:. There should be no fore/aft movement and it should not spin freely, or not move at all.

Will check it, but this is affected by road speed irrespective of gear, and affected by left hand and right hand bends - hence I think wheel or diff bearing?

Will check the VC though!

Ian , Your description does sound like a front bearing....... if it were me i'd change both sides, a set in mine only lasted just over a year before this happened:

they are cheap/easy to do (unlike the rears ! )

Andy - That was why I went there first, but could have sworn it would have been the offside!

May try the nearside next, using LD parts this time though, but I have a run to WSM on the 19th and I am a little nervous with this issue!

Do you know of a Rolling Road anywhere near you? The use of one would give you the opportunity to power up the car whilst you walk around it and listen for the noise? Offering the garage a few quid to use their RR would potentialy be quicker and cheaper than changing each bearing at a time.

Good luck

Nifty idea Bruce

Jacked it up, put it on stands and checked the diff and the rear wheel bearings, ultimately taking the drums off and checking the whole back end.

Diff is reconditioned (18 mths) with new front nosepiece bearing at the same time - there is a little play but no roughness or noise. Quality job from Hardys - so suspect this is not the problem.

Rear driveshafts and rear bearings were replaced at the same time but there does appear too much play in these - 1/16 - 1/8th of an inch fore and aft movement? So I suspect here is the problem - but again no roughness or noise apparent - other than the brake shoes rubbing the drum.

Point is - do I replace the hubs (some people do recon ones) - likely the same bearings as I used last time OR do I take the car off the road and send my hubs to LD or someone to get my bearings replaced with Timken or some other known make? These have lasted 18 months and about 6k miles only. Don't want to start the tale of sub-standard parts again - but what do you do?

Anybody got any hubs suitable for refurb and with circliped driveshafts??........ I could then get these done and a quick weekend swop over?

You said in your first post that the bearing was "noisy" but whilst investigating the rear bearings you noticed some play but no noise. Hmmm:?The problem you have is that checking the condition of a fully fitted bearing in an unloaded condition is very different from the loaded condition. This is one reason why I suggested the rolling road idea as the bearing would be under load (cars weight on them).

Good luck and I hope you are right in your suspicions.

The small bracket on the drag strut that holds the anti roll bar link hasnt snapped off by any chance.

Have you checked the condition of the six studs that hold the rear hub on? The movement isn't coming from there is it?

Checking with the hand brake applied will tell you if the back plate is loose. It shouldn't move, this will also confirm that the play is in the bearings.

Thanks for the help and suggestions, ended up taking it over to Stustag and we both listened. First time I've been in the Passenger seat!!

We suspected front nearside bearing, could even feel it through the floor in the passenger seat- so tonight I've replaced it (Thanks Peter @ LD for Prompt service!) and god was it shot!!!! 18 mths old, c. 6k miles and basically kn***ered.

2 hrs later and she's back in rude health and off to WSM and meeting withthe Bristol Area on Sunday with some other Worcs members.

Thanks Stu, thanks to all suggestions and help and lets hope the Popekeeps some good weather for the UK for the weekend?

Pleased you got it sorted so quickly. I trust you are going to replace the offside front bearing as well?

Bruce - did that one first - thought it was worse on left hand bends!

Both were not good - but the nearside was diabolical!
