I am getting a weird intermittent noise from underneath my Tiger. It is hard to explain, in that sometimes it sounds to me like something is loose and sort of grinds, or rubs roughly once in a while. It's not like a noisy bearing or U-Joint vibration or grind, which I have experienced on other cars I have owned. I took the Tiger into a local speed shop that I use on occasion, and they checked underneath everywhere, testing all bolts, and looking for cracks, for anything they thought it could have been, and it still makes this noise. I have the Dan Walters Torque Arm set up, but it checked out fine. The noise is intermittent, only while I am moving. It doesn’t seem to make a difference if the road is bumpy or smooth, I’m going around a corner, the speed I am going or accelerating or decelerating. I’m starting to wonder more and more if something is happening in my transmission or the rear end. It could have something to do with the positraction, so I’m going to put the car on axle stands on Friday, and change fluids in both, to see if that helps. My rear axle and/or transmission seems to whine a bit more at 60 mph, but that could be my imagination. Maybe it as simple as low fluid. My car doesn't leak much though.
I have been researching on the internet, and there are a lot of opinions as to what fluids to use, so will be studying that more this evening. For the tranny, David Kee says on his web site to use 75W-90 gear lubricant, or 80W-140 gear lubricant for more aggressive driving. With respect to rear end, I have seen people who say use GL-5 lubricants with built in friction modifiers for LSD, but there are different opinions on whether to use 75W90, 75W110 or 75W140. I assume this has something to do with the heat and heavy usage. I wonder though how the different viscosity effects the performance of the LSD
Any suggestions or thoughts on this would be appreciated.
