There is a 'thak' sound in my mehran right before the car starts accelerating in 1st and 2nd gear, sound disappears for later gears.
I got it diagnosed by a mechanic who said that the chassis right below the engine was rusted/cut resulting in the engine getting tilted and that gear foundation was broken, similar diagnoses was made by a different mechanic so I let him change the gear foundation and he also gets the chassis work done with help of a denter. However now the 'thak' sound while being a bit lowered is still there while accelerating, now my mechanic claims this as being a suspension issue and recommend me not fixing it as issue might come back after a couple of days, hardly makes any sense to me so looking forward for input from the experts here.
