Posted September 15, 20178 yr i drive an automatic and have a whinning noise when driving how do you check if my hrv is a inteligent 4 wheeldrive or a perminant 4 wheel drive what is the difference with a VTEC model jim
September 18, 20178 yr The HR-V should be the same as the CR-V for the 4WD function. It uses fluid pressure to measure any slip on the drive and applies it accordingly. The Diff fluid in the rear final drive should be changed periodically to ensure it doesn't degrade (a knocking when on full lock is the usual sign). Automatic transmissions can whine but if it is permanently doing it through all gears then I would be concerned as it may be a bearing on the way out. Worth having it checked over I would think
September 26, 20178 yr Author going into the shop tomorrow regards whinning is there any indication regards VTEC can the VIN be decoded to advise???? jim
September 27, 20178 yr VTEC is the camshaft variable control on the petrol engines and should be clearly stamped on the engine covers, etc This may shine some light on it https://en.wikibooks.org/wiki/Vehicle_Identification_Numbers_(VIN_codes)/Honda/VIN_Codes
October 6, 20178 yr Author bearing replaced on the near side drive shaft hoping that will cure the whinning - but it did not we are now thinking its in the gearbox and thats going to cost????????????
October 9, 20178 yr Maybe worth taking it to a transmission specialist to diagnose before flying into gearbox replacement as it may be something else within the driveline that's a cheap easy fix....worth a try
