rattling issues after flat towing, please help!

Very ticked right now....

Flat towed Jeep from Indiana to Idaho last week, followed manual, transfer case in neutral, manual Trans in gear, steering unlocked. Seemed to pull fine.

Went to take it to car wash today, and there is a horrible rattle/vibration when in gear. Smooth and quiet when clutch in.

Any ideas??? Haven't had time to check much other then crawl under in parking lot, drive shafts, u-joints etc all look good no slop.

Have a bad feeling it's Trans or clutch

Should have done nothing to tranny or clutch


What was spinning was both axles both driveshafts and parts of transfer case

That of course includes wheel bearings and all u joints

That is where I would look

You can isolate rear axle by removing rear drive shaft and doing general test drive in 4H if all is quite the Lilly rear driveshaft or axle

Check line levels in both axles the transfer case and just for grins the 5 SPd

Does it rattle going down ( moving forward) the road with clutch in?

Does it rattle rolling forward with clutch up and tranny in neutral?

That's what I thought too, but I guess I'll have to dig a bit to diagnose.
Front axle u-joints were just replaced so sure hope the towing didn't mess that up!! Same with drive shaft joints.

Pretty sure everything stopped rattling with clutch in.

Have to try clutch out and neutral though.

Thanks
Jeff

May have just broke the little clutch return spring clip. If it does it in neutral, crawl under the Jeep and see if you can determine where the noise is coming from.

If you have the NV3550, they can be loud with the clutch out.

Hoping to have some time to diagnose in next coupe days.

I checked fluid in both diffs through fill plug. (previously replaced last summer). Rear level was fine and looked good.

Front was a bit low (maybe 1/2"), and looked very metallic. Not a good sign I assume. Also, when I turn yoke on back of front diff, was some slop back and forth and something felt rough......ugh.

Removed front drive shaft, no change. U-joints were fairly new and still felt good, centering ball might need replaced but no slop.

Took for drive without front drive shaft. Still rattles and vibes, bad vibes over 40mph clutch in or out.

Going to open front diff to see what's going on in there next.

Any other thoughts?

Thanks guys

I just solved an irritating rattle on my jeep today.
The rattle would happen when first starting the jeep and when accelerating but would settle at a warm idle. Sound travels and this had nothing to do with towing but check your o2 sensors. The nuts which hold the sensor to the pipe was not fully secured and i just used a wrench to tighten the suckers and now the rattle is gone. Oh happy day! Best of luck though; nothing is more annoying than having a nice jeep with an ear sore.

Ok, more exploring tonight.

I pulled front diff cover and drained fluid, didn't look as bad as I thought, slight shavings on magnet plug but not bad, no chunks etc.

I could see the passenger side axle shaft was pushed in to where it was touching the pinion shaft. See pic, I hope I'm explaining it correctly.
Also looks like the bearing is not lined up correctly under the bearing cap on the passenger side.

Drivers side looks fine.

U-joints look good (new as of couple months ago), unit bearings also good.

Did something happen with shims on that side?

I am confused on how the axle could slide in that far to touch the pinion shaft??

Help please

You really need to try like what said above, sounds like a rear driveshaft u joint is toast. Had those exact same symptoms not 8 months ago and that was the cause. Can't say much about the pinion, if there are no metal chunks, not likely it is the cause.

Rear drive shaft u-joints are all fairly new. I clearly found an issue in front diff, but need advice before going further now that it's opened up.....
I will check it, once I figure out how to remedy this issue I just found.
Thanks Jeff

That's not the pinion shaft the axle is touching, it's the cross pin. I'm assuming the side gear is still on the axle shaft? Did the axle nut on that side come loose?

Yes sorry I was looking at a google diagram, apparently got my terms wrong

36mm axle nut is next on the list, I slid the entire assembly out last night attached to unit bearing.
Thanks!

Up in Canada for the week for meetings, hoping to fix things up once I'm back. The 36mm nut is the only thing I can think of that would cause the axle to slide too far in??....

36mm nut is tight.

Unit bearing is smooth and good.

If there is an issue with shims or carrier bearings could it cause the whole ring and pinion assembly to shift to the left???

I can turn the pinion where drive shaft connects by hand about 5 degrees, wheels on ground, and it sound crunchy inside.

Help!

If I can't get this sorted myself I might have to tow to a shop. Thinking of tossing in an Aussie locker while it's there...

Good luck man. I've been following the thread as I flat tow too. I'm just baffled. Like to see what happened especially, the cause.

I'm still learning on differentials but if a axel shaft snapped could it slide over like that into the cross pin?

Probably could, but I've slid the axle out and it looks perfect.

Well it sounds like there is no performance issue so maybe the problem is not what you think... check all of the exhaust heat shields they make the most obnoxious rattling sound ever and they can do it at times that make no sense.

Something is not right. The axle shaft shouldn't be riding on the cross pin.

Exactly.

First time I serviced the diff (changed fluid) everything looked good inside and def was not touching the pin like it is now. Something happened during towing, just don't know exactly what yet.

Maybe your pinion chipped a tooth and powdered , but as far as the shaft riding the cross pin that's goofy. Is it the right axle? Id take some measurements

I maybe completely off base but, aren't there c clips on the end of the axles in D30 front diffs?
Never mind, the c clips are on the D35 rear axles.

All gear teeth look perfect. Passenger side is touching.

I think I'm at the point of towing to a shop

Getting it towed over to Hazzard fab worx later this week, lets just hope it's not too bad.
From my brief description he said sounds like carrier bearings possibly.

Cross your fingers for me! I miss driving the Jeep!!
