SIKE30 0 Report post Posted October 25, 2006 Hi im thinkin of replacing the diff on my 1986 318i auto beacuse at the moment it has a diff whyne and it makes a clunking sound when I let go of the accelerator and i also leaks oil. The replacement diff I hav found is aslo from a 318i but it has a different ratio the ratio I have at the moment is 4.27 and the replacement diffs ratio is 4.47. Can anyone please tell me wat differeces I will notice when driving and how it will affect the car. Oh and im gettin the diff for $160 used Thank you Quote Share this post Link to post Share on other sites
Carl 3 Report post Posted October 25, 2006 You should accelerate faster and chew through a hell of alot more gas. $160 is at the higher end. Quote Share this post Link to post Share on other sites

In saying that you may find you are using higher gears than before. Quote Share this post Link to post Share on other sites
