Vibration on 4cyl 5spd

What's up guys so basically I'm getting a pretty mild vibration in 2nd gear at 20 to25 mph I just replaced my ps axle and input shalt and also the front pressed in control arm bushing... Everything else is tight suspension wise I work in a shop so I had it on the lift for the last few days and still confused as to. Why this is happening the car has 90k on it I'm thinking its the motor mounts so before I check and or replace them I wanna see If anyone else has had this issue ... The whole car shakes and then at 30mph back to smooth sailing and all other gears feel fine? Lemme know what you guys think

is it only in 2nd gear at 20-25? If its in all gear, check your tires.

Check tears in motor/trans mounts

Just in 2nd under load Trans mounts are fine all bushings are fine I'm probably gonna match the pass side and replace the driver side axle because bad inner cvs could be the issue as well

I've been battling vibration from 35-65MPH for months now. I replaced the driver's driveshaft about a month back, most of the bushings in the front end over the weekend. I picked up a replacement passenger driveshaft today and hope to install it very soon. If that doesn't fix the problem, there is only two things that will....a can of gas a box of matches.

Sadly I have the same issue..
2nd gear.. from like 15-35mph..
I just replaced both axles so I know it's definitely not that.
I do feel as if I need an alignment as I drive slammed and have hit a few potholes.
But Ricky I would try an alignment if everything looks fine with your suspension.

Mounts are hard to test on manual transmission.
I'd play around with the axle and see if the CV boot is ripped.
Also just visual check the mounts if you see any bulging or torn pieces.

My car does the same thing. Shakes a lot stops after 80 though... I got my tires balanced same thing after that and I know for a fact that my motor mounts are bad so maybe that can be the problem or even the axles.

Ya ,y mounts look good motor doesn't shake to bad and the axle is visually good that's why I'm confused but I'm gonna do the driver side axle and the driver side press in control arm bushing and see if that solves it ill let you guys know tomorrow

Was the drivers side axle replaced? I had the typical vibration under load when I bought my current car. After a certain speed and not under load, it went away. New drivers side axle fixed the problem. The old axle did not show any signs of wear or being defective
