Grease nipples on rear suspension linkages

What year did they stop installing these?
I have a 11' TE310 and it doesn't come with them, but my old 01 WR 250 had them.
I would grease them every ride as a precaution.
Has anyone put nipples on new type linkages and if so , is it hard to do?, is there a drilling already through to the top mount so that you don't need one also at the top?

Also I miss having axle pulls, does anyone make them specifically for Huskys?

This thread covers the topic somewhat;

Read the Thumpertalk link. It's not for the latest version of the rear linkage, but will give you a good idea of what's involved. The swingarm pivot is the same however.

Touratech http://www.touratech-usa.com/Store/927/Chassis makes axle pulls for the 2010's. I put them on my TXC. Don't know for certain they'll work on the 2011's with the new hubs but I suspect they will.

I drilled and installed grease fittings on the linkage of my 09 TE450. Was pretty easy. Still need to do the swingarm bearings, but considering a couple "best options" on how, exactly, to do it. Also switched to new needle bearings with the grease hole where that was needed (lower shock bearing, I think??). Ordered them from a bearing house, was not expensive.
