M800 issues

About quite some time back I ran over a road hump at the speed for 80KMPH and since then front left wheel of my M800 makes tacking sound, this sounds comes during the initial move and while taking the turns. As per MASS this is an issue with front left wheel drive shaft and I was asked to ignore it :eek:.

My car is running on 12” NEO wheels, Bridgestone Potenza G3 165/60R/12. Rear suspension has been raised a bit as after the upgrade of the wheels rear tire was scrapping the body wall. I feel the ride is not smoother, it’s little bumpy.

Engine response is not all that great, feels as if it’s struggling hard at initial stages at lower RPM :Frustrati. Gurus and BHPians please help me fix above issues.

Car – M800 CARB 1998, clocking 28K KM’s.
