Hello, i have a 2004 KZN165R Hilux SR5 the problem i have is in the front end, there is a clunking noise when traveling at low speeds between 20 and 60 km/h. the frequency of the noise is roughly every revolution of the wheels. I have changed the wheel bearings and seals on both sides but it hasn't stopped the noise. Also there is a delay when engauging 4WD after pressing the button on the transfer stick or selecting low range. Could these problems be related? This is the first hilux with fixed hubs that i have worked on (older hilux's with manual locking hubs and leaf springs are so much easier!) Can anyone please help me Thankyou
