Violent shaking under acceleration.
Posted: Wed Apr 12, 2017 10:03 pm
Hello all,
This is my first post in the fiestamk7 forums so bare with if i'm doing something wrong. I'm also an absolute n00b with cars, so anything learnt is from forums and word of mouth
.
So recently, i've lowered my car on some AP coilover units, and since then a whole host of problems has arose. Firstly, my car has a god awful creak like a wooden door when steering left and right when stationary or slow moving, i believe this to be the rubber bump stops rubbing against the rubber spring seating and strut cover i took off the OE shocks to place on the coilovers. Now I read online this could be the top mount bearings seizing after we rattled on the nut but it sounds like a rubber creak, leading me to believe its my bump stops. I still need to copper grease the rubber and possibly cut it down as I am running 55-60mm on the front.
Anyways, onto the main point, when under acceleration from a lower RPM (2nd usually), I can feel a very disturbing and violent shake from the vehicle and its slowly becoming worse. This issue is usually most noticeable on a smooth surface such as the newer tarmac roads. It almost feels like the car is wobbling like a wheel is buckled but its only really prominent in the lower rpm range (2000-4000). I'm sure it came on after I changed the disks and pads the other day after we had to hammer off the disk due to it seizing to the hub. Using a mallet we gave it a good beating from the faces and ended up prying it off with a chisel. Could this of bent my axel/cv joint or something? I would of thought it was my wheel balancing, but the symptoms disappear at higher speeds and RPMs (3rd-5th) which is completely different to my understanding of unbalanced wheels.
The only other way i could pin point the issue is when I have my foot slightly depressed on the clutch pedal and i can feel the car bouncing through that, possible fly wheel issue??
Any advice on where to take it and what to say? is this a simple CV joint thing or is it an engine/transmission problem?
Cheers, Nathan.
