Firstly - replacement bushes of this cars steering system is not cheap, the lower arm is massively built with extremely thick bushings which are expensive, but they work quite well for about 20 years. The ball joints and tie rods are very very cheap and easy to install too. The steering rack bushings are unique and require some work to install.
This car can sway from the back and you may think that its the front, to check find an open road and check the reaction of the car's body when swinging left and right at speeds of 30 or 40 km/h. The rear beam bushings do tear apart internally and your entire rear end can move causing your car to sway. (I would check those first as Pakistani cars usually have something done to their rear suspension). Also check the condition of the rear shock absorbers - if they are shot your car will have no road grip from the rear.
the bit about wheels I said is.
In a normal car the wheels bear the weight of the car at the lug nuts (corolla, civic, mehran etc etc). This car originally being a german design has lug bolts for the wheels.
The wheels carry the load at the round hole between the lug bolts, the bolts are there for the wheel to stay attached to the hub only. If the replacement alloy wheel is made such that the hub snout is not in contact with the edge of the hole in the wheel (too large hole) the weight is then carried by the bolts which makes it lugcentric - which will loosen and also has an inherent risk of running off centre too (out of balance).
Remedy is that to correctly diagnose your car put on the original wheels and tyres and check the suspension and steering behaviour.
