The recommended lubricant for TR6 trunnions (steering swivels) is gear oil. Unfortunately, it is difficult to fill the trunnions with the oil while the assembly is still on the car. There is a grease nipple on the trunnion (at the upper part) but typically using a grease gun loaded with oil results in a huge mess. An alternative is to use grease instead of oil but unless the trunnion is heated sufficiently to allow the grease to “melt” it will never flow far enough into the trunnion to do any good. Here is an approach to this task (original info courtesy of Odd Hedberg from Sweden). Obtain a Quicksilver brand grease gun from a Mercury Marine dealer which can be used to inject at high pressure Quicksilver gear oil from a tube which nicely mates to the gun. This results in no mess and no need to heat the trunnions.
- Quicksilver grease gun part number C-91-37299
- Quicksilver Gear Lube Super Duty part number 92-98780
- Mercury Marine is a world wide brand of power boating equipment and should be available just about anywhere.
