I had a bit of a lonk sound on my prop shaft when changing gears. A couple of my mates gave me advise.
Make sure you've greased the UJ joints.
Now look. It's the first time I've driven a car with a prop haft. I took me about a week the discover what and where it is.
Gone to Halfors and asked for a tin of the best. Got home to grease. Dressed in a overhall my mate gave me and armed with a tin of the best grease I dived under the truck.
I've filled my hands and grease the UJ it all the experiences I had. All of the UJ where covered with grease. You could not even see the joint.
Every impressed with myself I drive to my mate to show him how good I where.
He had a looked and burst into laughter. I've look at him very confused. Why are you laughing.????
When he got himself together he explained. You've have a number of nipples.
Nipple. (I'm a man of the church and he want to show me nipples) No No he explained. With have an number of grease nipples that need to to be filled with grease. He showed me all the nipples and handed me his grease gun.
Now half my truck's under body is full grease. On need for the WAXOIL.
So we learn.
PS. The Lonks it now gone.
