Gary,

I have never seen it written anywhere but there is a little understanding required when greasing our coaches.

What applies to mine, for example does not necessarily apply to yours because I have kingpins on my solid front axle, and drum type brakes on the drive. Some general rules that might help are understanding exactly what is being greased.

Steering linkages almost always have a protective rubber boot. I apply grease until I see a slight swelling of the rubber boot. The slack adjusters have a fitting at the slack adjuster itself that I grease until I see the most minute amount of grease visible, usually around the end of the shaft retainer ring. It may also appear at the adjuster release cap. I stop as soon as any is visible. The shaft from the slack adjuster going to the caliper only gets a small shot of grease and I never wait until it is visible. I think too much there can prevent the caliper from retracting and may hold the pads against the disc if you get too much in there.

I'm not at all familiar with the IFS so you may not even have grease fittings there, but at the pivot point of the wheels it is probable there will be grease fittings. If they do not have protective boots on those pivots I would grease until I saw evidence the grease made it through.
