Have a frog noise when I get on the gas in second and third- not always.
I also can feel a vibration when I lean on the shifter while driving. Could this be a half shaft going bad? Motor mount loose? Exhast looks okay. Anyone else ever hear this?
It is not the engine; I am thinking it is the exhaust or half shaft.
Only happens when I get on the gas when lugging- just staring out in 2nd or third.
?

 

what exacly are you trying to say..? leaning on your shifter isnt a good thing i think when you lean on it its your gears grinding so try not to do it anymore as for the sound.. have you always heard this sound?

 

I can feel a vibration while holding the shifter and slightly... slightly leaning on it.
THe vibration has been there since I bought it last year with 67,000 miles.
Have 77,000 now.
I have already replaced the front rotors, replaced and balanced the tires, and replaced front wheel bearings. I am thinking it has to be the half shaft on the pass side. Is this the side that gets the most wear?

Also have a vibration whiile running that is slight but annoying. aLMOST LIKE A TIRE IS OUT OF BALANCE. But they aren't. Wheels don't visually look bent.

Oh yeah I replaced the half shaft and intermediate shaft on the drivers side also.

The rotors smoothed out some vibration but still have the annoying vib. ??

 

hmm... maybe the manual transmission fluid need to be changed its about due for a change if you havent done that yet.... as for the other vibration i cant say i know whats going on
