Hello ladies and gentlemen, a pleasure to collaborate again. After a long time today I took my zforce 1000 sport to the workshop. They will solve the connection problem of the electric front differential. and also the other day I locked the rear differential. While driving, the rear differential locked and the wheel skidded. I tried to move backwards or forwards but the maximum travel was one meter. something must have gone wrong inside. I will let you know as soon as I have an answer to both problems.
