I recently had bad vibrations in my front end from 45-60 mph while accelerating. So I tore the whole front end down, replaced axles with new ones, lower control arms, outter tie rods, sway bar links, new dorman hubs, new timken bearings. The vibration is still there and way less than it was though. Any ideas would be very helpful. Car only has 82k miles on it

Are those the ones on the top of the strut where the three mounting studs go? Mine did spin pretty freely around when I took the strut out

So I think I have it narrowed down to the clutch or something clutch related, while going down the road if I barely lay my foot on the clutch pedal the vibration goes away, it's also doing it now on deceleration and when I got to work today and put car in neutral and let out of the clutch it started vibrating like crazy. 🥺

Is it a clutch you installed? If so what type is it?

Also, really good looking work, always nice to see a well taken care of SRT-4. Sometimes you see one that has a beautiful appearance and paint job, then in the suspension and behind the engine it is disaster city, rust and missing parts, etc. Good to see you putting a lot of effort into it, even if the problem isn't solved quite yet.

I know the feeling, I'm currently dealing with the distinct possibility of a ruined 500 dollar clutch...

with 105 miles on it

But, keeping my head up and working on other improvements, putting a bunch of new prothane bushings on currently.

have you checked the carrier bearing on the stub shaft?

Looks like a BFMIC. I'd guess the extra vibration is from the missing crash bar.

What bushings are those? Blue.....yummy lol. Where did you get them?

I have my eye on this DCR intermediate shaft with billet carrier and heavy duty bearing.

So coming back to this to reply to what I found was the issue. Was actually the throw out bearing. I could go down the road and barely press in the clutch and vibrations would go away. I replaced the whole clutch which was an act 6 puck, to an act HDSS full surface clutch and new trow out bearing, agp forged fork and new chromoly pivot ball. Issues went away. Throw out bearing had gotten so bad the car was vibrating horrible when letting out the clutch.

Got the whole suspension kit from rockauto and replaced it. Rides really good and every thing feels very tight again

Sweet, thanks for the info. Im going to get that kit. Was installing it difficult?

Nah it wasn't at all. Pretty straight forward with simple tools and an impact. Follow torque specs and you should be good to go.
