My 02 D4D Rav 4 has developed an intermittent (chunka-chunka-chunka?!?) noise and vibration from the rear when you are going around 50mph. A friend suggested it could be the universal joint on the propshaft so I had a look and it is very stiff and notchy. He said they were about a fiver for his Defender but I cant find them anywhere for a Rav 4 Anybody know where I can get one? Cheers
