Here is a copy of the email I sent to them when CW first put me onto this stuff.
Hi,
I have a Scammell Explorer break down tractor, a common problem with these vehicles is that the rear prop-shaft UJ breaks up with disastrous results. The prop-shaft angles are quite steep and the speed is high. The official MOD solution was to lubricate every 60 miles with oil. Most owners now use a modern grease, and lube every time they move! The grease always gets thrown out via the seals and a lot is needed to purge the joint each time.
Will your UHTEP grease help in this situation? One problem I can foresee is that of purging it through to push out all the old grease , would I have to take the joints apart?
Another problem I have with this vehicle is that the front wheel hub seals are unobtainable, and the brake shoes have become contaminated, will this grease stay in the hub if applied sparingly?
And their reply
Thank you for your inquiry.
I am sorry to hear of your problems with your vehicle! We do have a lot of inquiries regarding our U.H.T.E.P Grease, and so far every single one has been rectified using it. The grease is unbelievably sticky and its hard to convince potential customers how good it is without being able to show them. With regards to having the old grease still in there Tru Blu U.H.T.E.P Grease will stick to anything- including lower quality grease. I can understand parts being unobtainable for such a rare vehicle, but can assure you the grease will stay where it is put. For an example, we had a large gardening machinery company who could not put a warranty on one of their combine harvesters as the spindles were seizing due to the poor quality grease they were using was getting too hot and turning to liquid, causing the spindles to seize. They tried U.H.T.E.P Grease and they could put a two year warranty on that particular machine. Another example of the high quality of our products is that they are used by Ford New Holland Australia- An enormous plant company who manufacturer some enormous machines!
As you can see the answer sidesteps the question, but we all know that to get anything to stick there has to be a clean surface. I am going to strip and clean the hub bearings for that reason, will most likely just try a few goes with the props to see if it stays in better, before I pull them apart.
