I have a pulsing noise that I think is coming from my final drive on my 2002 gl1800. I found one on Ebay from a 2012 from a trike conversion. I need to know if this is interchangeable with the drive shaft and everything on the 2002 such as splines and swing arm. My 2002 has 85,000 miles and suddenly started making noise. Gear oil recently changed with Honda gear oil.
