Pivot bearing noise

[GoLefty!!]

Do the bearings rest on carbon seats or aluminium inserts bonded in place?

Let me know when you've sorted it out and I'll go riding with you again..

My previous "manufacturer" told me the bike wash products I used were 'too strong' and they ate away on the bearings grease and ran them dry, which eventually caused them to seize. I've had other full sus bikes and nothing like this was ever a problem.

 

First set of bearings installed in Germany were fine, until bike was serviced locally by this manufacturers agent.

 

Make sure it is definitely the pivot bearings.

Double check your rear wheel hub, and lower pivots (if any near the rear DR hanger)

 

Or get an FSR Spez!

I removed my pivot bearing and the suspension bearing and set of to Bearing Man to replace them. They asked me if I wanted the normal bearings or the premium bearings. Thinking that I don't want trouble later on, and that I want these bearings to last, I decided on the premium bearings. At R 88.00 a bearing, Is it worth it going for the premium sealed bearings?

Nope. Not worth replacing pivot bearings with anything from BMG - you need full complement bearings in there which you'll only get from Enduro via your LBS.

Only ever loctite a inner race of a bearing to a shaft - This to prevent the shaft spinning inside the race thus negating the bearing and destroying the shaft.

 

The only way to release loctite is to use heat or brute force, heat / brute force and carbon don't play well together so i would not recommend loctiting anything to carbon

 

 

Make sure it is VERY removable.... removing the bearing might well be an issue after this - rather try with a dry bearing and mount surface first - you could try meths to clean the surfaces first.

 

I thought there was only really one good use for Meths....

There is only one really good use for meths - keeping the fondue warm.....

It was an issue removing the existing bearings. It will almost be impossible to remove them if they were installed with locktite

It is not the thread lock product that loctite are well known for. The loctite 641 is a bearing retaining compound that is fit for purpose.

"A controlled-strength retaining compound that is ideal for cylindrical parts that require disassembly."

 

If you can replace bearings without the use of a bearing retaining compound that is ideal, but from the picture of the bearing the OP has put up it is clear he is getting some movement of that bearing, which could be the source of the noise. The retaining compound just helps to take up some of the slop and should help to limit the movement of that bearing and stop the noise. 

 

That bearing movement is most likely due to poor QC at the factory when the frame was made OR through damaged caused by replacing a bearing. Regardless of the cause, it would be best to try and limit the movement.

Ok removed the bearing today that were inserted with Grease, however there is that very distinctive Metal on Carbon creek when you press them in dry, a bit worrying as I never heard it when I greased the bearing outer into the carbon sleeve.?
