jim Posted September 15, 2017 Share Posted September 15, 2017 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 Quote Link to comment Share on other sites More sharing options...
Trevor Posted September 18, 2017 Share Posted September 18, 2017 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 Quote Link to comment Share on other sites More sharing options...

Trevor Posted September 27, 2017 Share Posted September 27, 2017 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 Quote Link to comment Share on other sites More sharing options...

Trevor Posted October 9, 2017 Share Posted October 9, 2017 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 Quote Link to comment Share on other sites More sharing options...
