check ur driveshafts 1st as they are the main signs of wear and tear that you are experiencing.
if this is not the case then doing a fresh rebuild is the best option
thats wat im currently doing. just replace everything and dont worry about it again. i no this sounds a bit pricey but its the best way. stops you from still worrying about the stock faults.
i get a lot of whinding from the rear diff and at very low speeds if i get on the clutch n off, i can hear my whole diff trying 2 lock and unlock. it gets really annoying sometimes
i just purchased a 4.44 mazda speed gear set off s2ki from a puddymod supplier :D literally 1 hour ago lol
next im ordering a j's crush collar, kaaz 1.5 way LSD and new bearings. after labour its costing me just under $3000 and its going to be MUCH stronger then stock, as long as its put together correctly.
