Need your advice experts, i m feeling some hardness and noise from car's suspension on rough roads. its been a long time i visited any service station, they used to apply diesel below the car, i think that is missing thats why shocks are dry and behaving like this. But i have read somewhere that its a bad practice to use diesel. Please advice me what should i use to clean and lubricate shocks/suspensions ?
P.s : 'Pre Soak' is very hard to find, Sacca is out of stock. Any other place to get it in lahore ?
