WOW, After reading all the complaints about Remco Driveshaft disconnects, I wonder if any of them actually own one! I operate a Nisson Xterra 2012 4X4, Auto, with a Remco disconnect, Roadmaster base plate, and Falcon2 towbar. This is the third Remco I have owned covering a period of twenty years of pulling toads. I noticed that most of the negative comments obviously were either improperly installed disconnects and/or the owner did not follow Remcos instruction as to how to engage or disengage unit.
The problems most people have with disconnects relates to DIY and/or incompetant installers. The installer must have a suitable high speed lathe capable of welding and/or balancing the modified driveshaft. To modify a drive shaft without balancing is a sure way to have problems. In addition most late model vehicles require shortning and welding of the shaft, which requires special equipment and traing. In most cases this is not simply a bolt on install as indicated by RV dealers. Most installers such as Camper's World and the typical RV dealer do not have lathes in their shops.
Solution: Insure the install is done by a experianced driveshaft machine shop that has performed this modification previously and has been trained by Remco or others.
Solution 2: Proper engagement of a correctly installed and maintained unit is smooth and precise, if done as directed by starting in neutral and engageing the disconnect similtaniously. If grease or other wet lubricants are not used in accordance with recommendations by Remco, the accumulation of dirt and grime on the disconnect is minimal and only requires cleaning with high pressure water spray and WD-40 annually or more often if excessive mud has accumulated. My experiance is that I clean the unit with a hose when cleaning car at car wash, semi-annually apply WD-40. Recently i switched to a dry lubricant spray formulated for RV slides sold by Campers world. This product works better than WD-40 because it is a dry lubricant, a rust preventative, and does not attract dust, dirt and grime.
During operation a properly installed and balanced driveshaft disconnect does not make any noise or vibration what-so-ever. The only indication of it's presence is the control knob on the floor under the seat. These units have been used by myself and others for decades of trouble free four down towing.
I am a high mileage RV'er towing my toad more than 20K a year. For me the Remco disconnect has enabled me to tow the vehicle I prefer without other consideration. I have had nothing but excellant performance from this product and would recommend this product to anyone.
I am not employed by or have no interest in Remco or and similar products, retailers, or installers.
