Or in the vacinity. I was thinking rear u-joint but it seems tight. I can't believe it's the rear end, as in differential. So far, I've only heard this thunk when the car is cold.
I had some noise in my rear end (no not that kind p ) turned out all but 3 of the bolts holding the ring gear were in the bottom of the housing, not holding the nice ring gear to the posi. Sheared the last 3 off in an attempt to do a burnout :eek2: Zoinks. At least you can unbolt a cover and look- 65 has a heavy pumpkin!
Heh heh... Just a general thunk, and I've pretty much narrowed it down to the rearend. It feels like "slop" in the driveline somewhere. Well, with a 340-2 there won't be any burnouts in my future...
rearend noise Need more info. cold clunk. well put your foot on the brake and torque the motor on and off a bit and see if there is a clunk. trans mount bushing in the rear suspension shifting etc. Check out the spider gear for excesive wear. They may be binding with lack of fluid cold start. axle bearings check for up down play. There are a ton of things that can cause a clunk in the rear. Does it do it alot when you go from drive to reverse with the foot on the brake? Check all these things and get back. Jim
oh yah... Check out your rear brake shoes for release. They maybe sticking to the drum! seen that alot. Jim
Jim, many thanks for the replies. I notice this thunk when approaching a stop as the transmission downshifts, as if a shock is being passed through the drivetrain. At first, it only happened on the first downshift of the day, now it's more constant. I'll be under the car all day installing duals so I'll take another look at things.
Maybe set the emergency brake, place in neutral and then grab hold of the driveshaft to 'feel' for ring/pinion backlash or you may want to pull the diff cover and inspect/measure-good luck
How do you mean? You reached under there and yanked on it? You don't have nearly as much muscle as the engine. Make sure the u-joint is really OK
