Today, i went to engage the rear pto and when i placed xmsn selector in 1-5, i heard clunk as the xmsn engaged. I went ahead and operated the rear winch, which took about 10 min total. I placed the xmsn in N, then discussed the troubleshooting with the wife. I crawled under the tck, had her put the xmsn in gear, then back to neutral numerous times, listening and feeling the xmsn, driveshaft and t-case. I could determine which component it could be, but ruled out the driveshaft since the joints were tight.
I did notice the xmsn pan was hot, as was the xmsn tailhousing, but xfr case was barely warm to the touch. I didnt temp gun the xmsn, but the gauge showed around 125F.
I decided to pull the tc drain plug and after looking at the black colored oil, decided to catch it for screening. After the oil was drained, i ran a pencil magnet in the drain port and pulled out some concerning ferrous particles.
2 pieces were very thin and about the size of thumb nail. 1 piece was about 1/16”thick and wide, and about 1/8” long. The rest looked like course ground pepper size gold flakes, but were of a ferrous metal.
I filled the tc with part wash solvent and took it for a 1/4 mile drive and pulled the plug and got more metallic flakes
See attached pics, and sorry for poor clarity.
Should i be concerned of an impending failure?
Any idea of the possible clunking cause? I never noticed the sound before, but thats not to say it hasnt been there the 2yrs iv had the tck, i just never noticed it till today.
I will change the xmsn oil and filter mid jan when i get back from work. But the xmsn oil is clear and smells like fresh motor oil, no burned smell.
