Guys-
what is the reasoning behind using 90W in the trunnions as opposed to grease? I would think a synthetic grease would offer superior protection. Comments from those that know?
Thanks....
 
I'm told that grease won't flow well enough to lubricate the trunnions. I tried using very light weight grease in them on my GT6, but they wore out. Whether this is soley due to the grease I can't say, as I don't know how old the trunnions were when I got the car. Do a search for trunnion oiling - somewhere there's an article about an oiling gun meant for outboard motors that's supposed to be much more convenient for doing the job.
 
I think you'll find that grease was specified for TR2, 3 & 4 trunnions -- later TRs called for oil. Your lube chart may refer to them as 'steering swivels'.

I have always used grease.
 
Hi guys, I can't quite remember where I read this but if you apply a slight amount of heat over the trunion with a propane torch just before you grease the trunion, the grease will flow. I tried it and it seems to work. Just go easy with the heat.
 
I, too have always used grease. I rebuilt the suspension over 25 yrs ago and the trunions are still good.
 
One possible problem with using grease in the trunnions is that it may cake up, or solidify, with age and lose some of it's lubricating properties -- not good for trunnions which need constant lubrication.

Hope this helps!

Right ! Not only that, the trunnion design changed considerably ... TR2-4 trunnions are generally NOT oil-tight.

The grease of the day had a definite tendency to harden and cake, the result could be poor trunnion lubrication. Modern greases are much better about this, so I don't see it as an issue any more.
