Today we put a bumper on Alyson's truck. When she left, she heard a light tapping sound at low speeds that could be heard from the center console area. It was road speed related, not engine speed. After driving a few miles and getting everything hot we couldn't hear it anymore.
I actually thought it most sounded like a failing speedo cable, but I don't think the D2 has a mechanical speedo - I believe it's electronic so no cable to make noise.
Of course on a D2 you always think about u-joints. I asked her when they were last greased and she thought it was done at the last service. We pulled it back in the shop and crawled under. I pumped a couple shots into the front u-joint, but the joints at the t-case are non-serviceable. Worse yet, I actually found one of the caps had a small chunk missing out of it.
I don't know if that u-joint was the cause of the noise, but clearly they need to be replaced. It's not a huge job, but not something she's going to take on at her apartment and she doesn't want to drive all the way up here again to do it. Anybody closer want to help her change some u-joints?
Graeme, do you happen to have them in stock?
