Martin White Posted November 7, 2020 Report Share Posted November 7, 2020 Hi Folks Just getting around to looking at front suspension in new car. On the right side there appears to be a grease nipple for the trunnion but also one at the top of the suspension? The left side foes not have the grease nipple at the top of the suspension and does not have one at the bottom either. Where the grease nipple at the bottom should be is a hex nut. The top two photos are the right hand side Any thoughts? Please see attached photos Link to comment Share on other sites More sharing options...
JohnD Posted November 7, 2020 Report Share Posted November 7, 2020 The blanking plug for oiling the trunnion is how they left the factory, I believe. Take it out, put a nipple in and oil, remove and replace the plug. I don't think the nipple on the top joint is original, but a good idea!

Martin White Posted November 7, 2020 Author Report Share Posted November 7, 2020 Thanks John. Could I just leave the nipple in like the right hand side? Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 7, 2020 Report Share Posted November 7, 2020 some top ball joints are supplied with a nipple to re grease as a service item some are not allegedly this is sealed for life ...questionable track rod ends are also available with/without nipples some may say a nipple can allow water in if the small ball doesnt seal, i have always replaced the hex plugs with nipples and oiled or greased ,and left the nipples in place . the trunions must be oiled with ep90 or 140 never greased there is also a plug on the rear drive shaft housing ( non rotoflflex) this is greased not oiled one reason some have two grease guns on for oiling one for greasing so oil trunions ep90 GL4 same as gearbox and diff . grease rear hubs , steering rack , any ball joint thats greasable, propshafts , drive shafts ( if greaser is fitted or can be fitted) grease front hubs just the bearings (no nipples or plugs) dont fill the hub cavity that just traps heat Pete Link to comment Share on other sites More sharing options...

Chris Longhurst Posted November 7, 2020 Report Share Posted November 7, 2020 I leave them in place on the suspension but put a rubber cover in place (the covers can also be used on brake nipples to stop dust & dirt getting in). Plenty on eBay - example:- https://www.ebay.co.uk/itm/10-UNIVERSAL-RUBBER-BLEED-NIPPLE-PIPE-COVERS-BLEED-SCREW-COVERS-GREASE-CAPS/124332539498?hash=item1cf2cbfe6a:g:ToEAAOSwyedfWfvS I'm sure they are available from many other suppliers.
