Thanks for your reply. Will be changing it out this week with a Gates Pulley 36087. Had a Dayco but lasted maybe 30,000 KM. Unfortunately I am not sure of the reassembly of spacer and washer but will give it a long look. Sadly I am only continuing to keep working on because any new vehicle I am trying to buy is not available till late Fall 2022. Would love to be able to keep the Pathfinder but horrible gas mileage and getting a bit old to trust on longer journeys.

Which side of an Idler Pulley is the front? Dayco 89134 or similar. If orientation matters why do pulleys not state somewhere on part? This seems to be a sealed bearing so I have not used the Dust Covers due to interference. I have it in this order. Spacer, Pulley, Washer, Nut. Is this correct? Belt is aligned. Thanks

Been having same problem, 1999 Pathfinder. Vibration in front end from 60 kmph to 100 kmph (40-60 mph). I checked everything and the only thing that stops it is removing front drive shaft. If you do remove it make sure to mark it so it can be reinstalled in the same position. I have been told it is probably Transfer Case Bearing or Bearings. A few comments I received: " I suspect the bearings as well. There should not be any noticeable end play at the drive shaft flange on the transfer case. There is a front and rear bearing in the transfer case for the front drive shaft. Both are suspect. To replace them requires the transfer case to be disassembled. The factory service manual has a good write up for overhauling the transfer case and specialty tools that would be needed." " Those bearings are pressed onto the drive shaft in the transfer case. The bearing and shaft assembly needs to be removed from the disassembled case in order to use a puller to take the bearings off of the shaft." I have not gone any further with this. I will try replacing front Drive Shaft and if that does not work I will have to park it till I decide next step. I find it strange that other than the vibration which is only at at the speeds mentioned, it runs fine. No noise from Transfer Case, Shifts fine and No leaks from Transfer Case. Let me know what your findings are.

Were you able to reach KS connector from underneath? Will the connector (if successful at unplugging) fit on a New KS? I am unsure if there is a pig tail on the old KS. Thanks, Mark
