Call Ahram (06 5396988) guys in sharjah for best price in ford spare parts. Im buying myself from them.
If axle is having no issues, then why change. Sometime this turning guys do good job and problem never re appear. Just make sure you change axle boot in time when they are torn or cracked and start loosing the grease. Thats the main issue of loosing axle completely when axle run dry and with road sand and grit.
