Re: Strange sound when taking a u-turn or right turn in maruti alto
It is probably the left side drive shaft related issue.
Left turn + kat-kat noise = right side drive shaft problem
right turn + kat-kat noise = left side drive shaft problem
Usually replacing the drive shaft is the right solution, but again depends on how long you have used the car. What is the odometer reading of your car?
Here is a pic of Palio drive shaft - (in somewhat good condition)
Here is a pic of the MGP packing for M800 drive shaft & the next pic is of the contents in it.
There is no point in replacing the drive shaft boots (costing about 500/-) if your car has already covered more than 50K kms. Although it very much depends on how & where you drive the car, still I would anyday suggest replacing the complete shaft instead of just the boots. Labour cost remains almost same for both the works. Skip VR brand use MGP, even Delphi is not that good.
Also almost all local garages will suggest you to try "Reekan" drive shafts (local slang for re-con/ re-conditioned), these are basically old drive whafts whose CV joints are replaced by cutting & welding. Not worth a penny though.
