Maybe a noob question but does this need any servicing in the way of greasing?
Thanks in advance.
Its still an idea I believe to check them from time to time to make sure they move freely but as SM25T states, they are maintenance free.
And I'm stunned to still find both of mine are in good working order, 19 years and 50,000 miles on crap roads later in all weathers, with several years of no garaging . . .
Thanks to all, I did wonder if they were sealed. It's a far cry from my old Triumph Spitfire trunnions...thank God!
Just a regular external clean with a light application of WD40 (other similar products are available) to keep the crud down.
Beware - they do wear but I think it is due to how the suspension is set up & the duress they come under - constant track driving etc.
If all wheel bearing play has been eliminated the easiest way to check for wear - if you are nimble - is to raise the front of the car up, place one hand at the top of the tyre (12:00) & the other at the bottom (18:00) but with the palm far enough inboard for the middle finger to touch the bearing. Then try to move the wheel in & out vertically if there is any play your finger will know!
Otherwise have an assistant 'wobble' the wheel while you inspect the bearing.
That sounds a good tip, thanks Geoff
As an industrial specifier and user of such devices, this is pretty standard advice from suppliers of this type of bearing:
Lubrication of Steel-On-PTFE Spherical Plain Bearings
For steel-on-PTFE lined (fabric or composite) spherical plain bearings, there should not be any additional lubrication added. Any lubrication of the sliding contact surfaces could disturb the internal self-lubricating properties and shorten bearing life. Therefore, lubrication of these bearings is not advisable.
Very superior garage floor, most impressive.
