I recently swapped enginemounts and transmount on my car because I thought this was the reason why acceleration often is very jumpy. But imagine my dissappointment when I went out driving and it was still doing it!! Even without pressing the gaspedal (but 1st gear in place) it often sort of "jumps" forward. Feels like riding a camel or something

Feels like there is play in the drivetrain somwhere.
Does anyone have any idéa what is causing this jumpy ride?

 

did you use the right bolts installing them. Maybe its some loose bolts connecting your drive shaft to your differential

 

Yes I used the original bolts and tightened everything very thoroughly. So I seriously doubt it's loose bolts... atleast not on the parts I just swapped. If I were to guess I'd say it feels like there is some play in between tranmission and all the way to the wheels... somewhere.... but where??? I've noticed this phenomena on other older sports cars but not as violent as this.

 

Maybe need new shocks and struts
play somewhere in suspension is a possibility to.

 

Yes I think that could also be it.... Are there any other signs that would point to this? I mean it doesn't handle bad when I drive it hard in curves...but then again I don't really have anything to compare it to. And I know the rear struts are new so it aint them. But the springs... how can you tell when they are too worn?

 

As for the shocks a bounce test will eliminate them, for the springs basically when your cars going down the road looking like your hauling a load of firewood in the back thats when they need replacing

 

Then no way is it the springs! Are there any gears or something inside the axel that tend to get so worn they cause play??
