Good Day Guys, As the title says, did refurbishment of my control arms at Titans abt 1.5 months ago.Yes, it is a cost cutting measure with proven results. Instead of changing the entire control arms, they can press back the ball joints & fabricate and replace the spolit bush. \Material used for the fabricate the new bush is aluminium sleeves, universal aluminium ball joints & teflon.Results doing this is on my e38 is elimination of vibration when braking, crispier & tighter steering feel & response. Cost of doing this is RM200 - RM250 per pair inclusive of installation & it takes half day to do it . Believe it is half of the cost of changing to a pair new OEM control arm.\Thks.
