Murphy's Law Strikes on road trip - Clicking, squeaking from RR tire, what now?
(story - tech part below)
So, its memorial day weekend. Going to visit my girlfriend's Mom in Wikes-Barre PA from Boston, 330 miles round trip. This is the cars first big road trip after driving it around home for a few k. Checked everything, packed the car, left work early and we're on the road. Both of us are excited for the first big trip in the car i've worked on tirelessly for 18 months... Huge smile on my face for the first 250 miles. Nothing but cruising with the sunroof open down I-84 at 60mph. Wonderful! Cross over into PA, I thinking everything is going to be fine, were making good time. 26-27 mpg on B100, and the odometer is spot on....sweet. 20 miles over the PA border I hear something intermittently clicking and then banging from the RR. at first I thought the RR door was loose wasn't that. stopped, took off tire and checked everything (had all my tools  ). axles fine (new CVJ's), sway link fine, flex disc (new) fine, springs and shocks fine. no sound bouncing the car up and down. all bolts tight. eventually, i *thought* the problem was the e brake cable being loose, vibrating and hitting the driveshaft or the subframe. shored it up and limped into Wilkes-Barre. went to the auto parts store next AM and got under there and secured the brake cable. re-tensioned the e brake as well. ran car on jack stands. went for a test drive. all is well. thought i had it... drive home yesterday went just the same as the drive out. fine for 250 miles, and then the sound comes back again. went to look under and my repairs didn't look any different - nothing had moved or looked like it was distressed. had dinner at the Blue Colony Diner on I-84, put another zip tie on for good measure to tighten even more. no sound till we are 30 miles from home....and it comes back. all my repairs still in place, im thinking its NOT the e brake cable. parked car in the garage to await further diagnosis. (tech summary) so in summary - -clicking, light banging from RR. intermittent. sounds like something light (like an e brake cable) is loose banging, not heavy machinery like a diff, bearing, or axle. -seems to only happen after long periods of driving, but that may be a red herring -rear end is essentially new in last 3k miles, replaced in stages,but no problems until this trip Any ideas on where to look next? Thanks for listening, dd

only thing I can think of is the axle... perhaps you have a pinhole in one of your boots, and it's getting hot after a long drive and expansion is causing it to click?
also possible is the ebrake shoes are damaged, and after heating up they contact something? or heat could be causing the rear bearings to start to click... get a good floor jack and carry it around with you, drive until you hear the noise, then park and quickly jack up the wheel and spin the tire by hand and see if you can locate the noise. carry wheel chocks with you and possibly even a jack stand or at least throw the spare under the side of the car for some protection from the car falling off the jack...

Clicking
One of the new CVJs in my '85 300D-T (W123) started clicking after 500 miles into a trip last summer. Steve at CVJ told me (via long-distance phone from Winnemucca) that one of the balls in the joint might be popping out of place and then popping back into place. He said to ignore the noise. I was nervous but continued the trip (not much else to do) and 500 miles later, the noise stopped. Almost a year and several thousand miles later, the noise has never come back -- go figure.

My SD encountered a problem almost similar to that and the mechanic found out that the axle bearing was the culprit. It only showed during a long trip.

Cool, Ill give CVJ a call.
Lets see what they say. Im still under warranty, but Im not excited about re-doing a rear axle job.
Second time around it'll be fast... Maybe I should switch to a 2.88 diff while Im at it. Even with all the grease packed in there you can get that really bad clanging? Yikes. dd

It's either this
http://www.peachparts.com/Wikka/W123RearAxles Or this http://www.peachparts.com/Wikka/W123RearWheelBearings Dave PS Sorry, just showing off. Probably the axle, check the boots and try the grease first.

Thanks for the replies.
Took car out of the garage for a ride today...no noise. Axle im hoping. I dont think a bearing could make a noise like I heard. Bearing groan, right? New warranty axle on the way free-of-charge from CVJ. Woohoo I get to do the rear axle job again! Actually this time it'll be easy...having done it once itll take me an afternoon. Anyone have a 2.88 diff to swap in :-) I guess I should take this as an opportunity for improvement... dd
