Clunk,clunk in CJ 4 lo?
Was out in my 81 CJ yesterday, all was fine on the road, all was fine on
the gravel road, went down a very steep switch back road to a lake,1st gear
4 lo, idled down, all was fine, coming back up I started noticing a clunk,
clunk, clunk, about a second apart, one of those noises you have to
listen/feel for, only happened on heavy load, when I came to a flat spot it
went away, another steep part and back it came. Anyway I continued up the
trail the other way from logging road to see were it went, also trying to
find out about clunk. Only under heavy load, seems to be only in 1st lo, but
on these roads I may not be able to hear it or get it under enough load in
2nd, also tried 2 wheel drive under load, not there, also tried 4 hi, but
like 2nd lo pretty hard to tell or get it under enough load without going
too fast for road. Coming back down that trail in lo, 1st, I could hear/feel
it again, so something happened in the 10 minutes of going down one trail,
turning around and coming back up.
All was fine again coming home, on logging road and paved, so it sort of
sounds like it's down to front driveshaft, or is there a gear, ( dana 300 )
that is only turning in 4 lo that maybe lost a tooth? Too dark when I got
home to look at front driveshaft, hopping it's just a U-joint, but thought I
would run it through news group too.

Re: Clunk,clunk in CJ 4 lo?
Ok never mind, I climbed under and rattled front driveshaft, so that
answers that question. Funny a freind just bought a YJ last month, I climbed
under and saw his front drive shaft U joint with no caps left, so helped him
replace them, then my daughter comes home and said her tranny is making a
humming noise, I climbed under and saw no caps left in her driveshaft, this
was a 1 year old D. cardon, supposedly sealed universals, no grease fitting,
anyway it must be that time of year or something.

Re: Clunk,clunk in CJ 4 lo?
Glad you found the problem but while you're under there check your
tranny mount. After 25 years of heat and leaked oil it is probably
ready to come apart. The first thing I thought of when you described
the noise was that your mount had broken loose and allowed the tranny
tail to slide over enough to allow the rear U-joint in the front shaft
to hit the tranny tunnel.

Re: Clunk,clunk in CJ 4 lo?
Don't you just 'love' those POS 'lifetime' sealed u-joints?
When I am in full wheeling mode, I only get about 8 months out of them,
maybe a year. I went back to the cheaper greaseable ones. No more
issues.
Canadian Tire took all 7 that I could find receipts for back.
