I'm driving a 1995 Honda Civic LX 1.6 now. I had a used transmission installed and as I understand the mechanic who did it forgot to put the clips back in the right places. While driving the whole front passenger side driveaxle(hope that is the right part I'm talking about)basically came out of the transmission. I noticed all the grease all over ther place. The newer mechanic went ahead and put a new boot in. It ran good for while, but now it makes a thumping noise at that area. I was told it could be the bearings are worn out. Any suggestions? Thanks for any suggestions.
