When pressing accelerator steering pulls to the right and when brakingor accelerating knocking sound coming from front left wheel

get the car serviced, bad noises can be a sign of great danger to you and (well ALL)

• bad brakes
• bad front wheel bearings.
• bad suspension and related steering parts.

nobody in a silly text box can drive your car and for sure diagnose that at all, 3000+ parts there.
find a human to test it , hands on full inspection of your car.
do it now. be safe.

could be a differential problem, or half shaft broken where power is only going ot one wheel. when the car accelerates the wheel with power can cause the vehicle to jerk. could also be a wheel problem. ensure the tyres are inflated correctly. is the steering wheel straight or turned to one side when driving in a straight line. if turned there may be damage to the steering system. did the symptom start after another person has driven the vehicle? or after an accident or driving into a curb or off road? all these may be factors to the problem. if not the case try rotating the wheels front left to rear right and front right to rear left to see if the problem disapears. if persists seek professional to test drive the vehicle and give an appraisal to the cause.

I hope this was helpful.

CV joint - wheel side needs to be replaced :) right wheel, a lot of people drive like that for a while before they fix it so don't worry, also it shouldn't be soooo expensive

If it is PULLING to the right, is it STEERING or TORQUE that is pulling it?

What I mean is this... If ONLY your Right Front Wheel is pulling with the Acceleration and the LEFT is not,m you will have a Torque Pull,

You may have a problem with your
a. Left CV Axle
b. Transaxle Internal Failure

First check wheel bearing. Jack front end up lifting tires off ground and see if the wheel moves by pulling on the sidewall part of wheel from top and pushing bottom towards the car does this back and forth if there is play, wheel bearing could need replaced. Take tire off and check for loose brakes, loose calipers, loose dust shields , etc. everything except rotor should be tight.

Hi,
The problem in the acceleration might be the electronic governor and the clutch have to be replace. ur nearest service center would check on it thoroughly, its a bit expensive and a experience Renault technician is needed! The front wheel alignment should be checked again, as u said somebody have tinkered on ur steering! Tell them to check the front wheel alignment(toe-in/toe-out) and the cambering. Ask them to show the result of computer wheel alignment. Wheel balancing is for the tyres only, not the steering!
Hope that Fixya up!

Your car needs a front wheel alighnment.When it pulls under acceleration and then goes the other way,get an alighnment.Torque pulls the wheels one way and then the travelling pulls it the other.Hope this helps

If you are driving any front wheel drive vehicle, what you are feeling is called torque steer....sometimes it's from poor design but it can also be caused by a broken engine or transmission mount allowing the engine/trans assembly to shift under load or when removing load.
You can do a quick test by holding the brake down firmly and in gear, press down on the gas. have someone watch (from the side of the car ONLY) and see if the engine shifts. Do in both drive and reverse.
Be very careful when doing this that the car does not get away from you and do not hold power for more than about fifteen seconds at a time or it can overheat the transmission. This only works in automatic trans cars... for stickshift ones you need to move the engine with a long pry bar.

Lou,I belive your right.When an axle goes this is the sound they make.
