Paul Hig Posted January 3 Report Share Posted January 3 Spec says use oil to lube trunnions, but how do you get oil in with a grease gun?. Also, I've heard some use grease not oil, so what's the view on this? Quote Link to post Share on other sites
RogerH Posted January 3 Report Share Posted January 3 Hi Paul, the early cars used grease and it work OK. Later cars use a thick oil - semi fluid grease. Use a grease gun to fill. Roger Quote Link to post Share on other sites

Andy Moltu Posted January 4 Report Share Posted January 4 Grease for me. A lot of repro trunnions are not well sealed around the “cap” at the bottom and oil will drain out. Why Triumph swapped from grease to semi-fluid grease/gear oil is unclear. Quote Link to post Share on other sites

Modern greases don't dry out and go hard like they did in the 50s. Although not a TR6 my experience with my daily driver TR2 front suspension is relevant. I rebuilt this car between 1980 and 83. It has done well over 200,000 miles (320,000 kms) since. The trunnions, top ball joints, idler and tie rod ends are what I fitted back in the early 80s. They are still in fine condition. I apply a grease gun to everything at least a couple of times a year, whenever the front wheels are off. Edited January 7 by John McCormack Quote Link to post Share on other sites
Richard Pope Posted January 9 Report Share Posted January 9 After reading countless posts on this forum suggesting everything, I settled on CV grease! Quote Link to post Share on other sites

Andy Moltu Posted January 10 Report Share Posted January 10 The key is to lube regularly. I'm in the grease camp. Twice a year even if you have done negligible mileage and don't skimp, over filling with oil or grease helps to push or wash out any grit or debris that might have got past the seal. If you opt for oil you need to be sure the trunnions are sealed at the bottom "cap" as it won't stick around like grease. Many repros in the past weren't great.
