Basically all it is is a slight but very noticeable shudder/shake when the vehicle is accelerating between 25 and 35 mph. it does not happen when slowing down. I bought my crv used and had a carfax done on it. it has had previous front strut damage that has been repaired. The shuddering started a few weeks ago when i took the truck to a friend/mechanic. i trust him 100% and he does great work. he replaced the front right cv axle and when i picked it up it first started shaking. so i brought it back to him and he said the only thing it could be is the axle so he warrantied it out as defective and put in a new one free of charge. the shaking was still there though after he replaced it and he said he would research it. he thought it could possibly be the clutch wearing out but the shaking in this specific manor is not a typical symptom of a wearing clutch. please let me know if any of you have experienced this same issue. i have used this website alot for getting answers to questions but have never needed to post any new questions.
