Hello, I own a 90 Shelby Daytona with the 2.5 T1 motor and auto trans. I've owned this car for 7-8 yrs and it's always had this issue. During moderate and harder acceleration it feels and sounds like something under the front end is thumping. It not a clicking sound like when cv joints go bad. Nothing underneath is loose that I have ever been able to find. Anybody have any ideas? Tia for any replies.
Wow! I searched for others who had experienced this issue in the past but nothing showed up until I made my post. Now I find similar posts shown under my post. I guess now I have all the info I need.
Pop in some axles. or figure out which side is making the noise. axles are about 60$ from napa. and putting them in is a 20 minute job.

It's not popping. It could possibly be one of the inner cv's as I installed both 1/2 shafts myself and they are reman. units. But this car has done this since before I bought it about 8 yrs ago. The previous owner, I seem to remember, told me he thought it needed new motor mounts. I will be getting a set tomorrow when they arrive at Napa. From what I've read on here, I think my motor mounts are suspect, plus they are pretty old and cracked it looks like. If this doesn't get it then I'll move on to buying brand new 1/2 shafts.
Replacing the motor mounts and especially the transmission mount solved the problem. More knowledge gained.
