did you add the posi additive to the rear end? this may be whats causing it. also it could be your wheel bearings doing the same thing. take the wheel and brake drum off and lif up and down on the axle shaft if it moves more than a 16th of an inch this could do it as well but you would notice vibration from the rear of the car while driving. or a brake shoe retainer spring and clip have broke off and is catching on the shoe causeing the same noise.

try this first there is a adjustment clip on the cable by the carb some you push like a button others are a bit different. "with the car off and in park" have someone hold the button down and push your gas pedal to the floor and hold it there. then have the helper remove his hand from the button. then remove foot from gas pedal. this should reset you cable to where it needs to be. if that does not work then check the line pressures and adjust from there.

actually there is a product called bombs away this stuff does an amazing job on chrome, aluminum, stainless etc. it is well worth the price plus you dont need to use alot of it to polish anything my step dad used 10 milliliters to do his whole motorcycle.

i would purchase a few sets myself.

also make sure you get the later model trans 85- newer as some were the old design and were weak. do a seach in transmission forum for that info Alex

see tech info page http://www.firstgenmc.com/tech/bodytagdecoding.shtml Alex

There are 2 types of th350s long tail shaft and short shaft "the long tail is for trucks" this is why i asked as the wrong type of tranny put in or wrong drive shaft lenth can cause this. alex

is the tranny the original one "short output shaft cover type" or is it a replacement with a longer out put shaft cover? also what is the measurement of your drive shaft from center of u joint holes to center of u joint holes Alex i will measure mine tonight and let you know my measurement.

i like andreas idea lol just need to get some decals for the HHR

http://www.firstgenmc.com/tech/rearaxledecoding.shtml heres a link Alex

err i stand corrected. I forgot about the baking of the rod and piston and freezing of the connecting rod. my appologies

bushed rods dont exist.... bushed wrist pin piston holes are what you are refering to where the piston is made to where the pin slides in verses being pressed in and uses spirolocs/ inside spring clips to hold them in the piston. the rod end is the same size either way and slides on. If the connecting rod was made loose the rod would break and destroy the engine. "i dont think a manufacturer would want to pay for a motor that blew because of that design would you?" Alex

under the front seats or the back seat or on top of the gas tank "i found mine on the gas tank" the first one i threw away and kicked myself for a week after i found out what it was. glad i found another one though and it was the last one on the car. Alex

my car shrunk in the wash but here i am at the 2006 eastern meet. here is a car that is technically mine as andreas once said lol

looks to be an eaton.... what does it say on the carrier? Mike you are correct on all accounts but depending on the type of carrier it may not be rebuildable. Eatons are rebuildable Auburns may not be. eatons use a clutch pad "friction discs" and springs to stay engauged. Auburns i beleive use cones or another method. to rebuild a unit requires a case spreader to remove and reinstall the carrier "this aides in not damaging the bearings on the carrier" you will also need a axle bearing puller "unless your housing has c-clip eliminator axle bearings which you will need to take to a machine shop to remove as they are pressed on the axle shafts. parts needed for a complete rearend rebuild 2 wheel bearings 2 wheel bearing seals "unless yours has the c-clip eliminator bearings" 1 inner pinion bearing "also comes with a new race" 1 outer pinion bearing "also comes with a new race" 1 crush sleeve "available at the dealership" 1 pinion seal 1 posi traction rebuild kit " this should come with the new carrier bearings and races clutch disc pack and springs, shims and a few other things" check to make sure it has all you need in it. 1 cover gasket "try to keep old one in good condition and take it with you to make sure the gasket is the correct size. 90 weight gear oil gm positraction additive "available at dealership" there is a plug on the passenger side of the housing. that is the fill hole. fill it up to the plug hole to where a little runs out the hole. follow the directions exactly on the posi additive container. this will make sure you rebuilt carrier will last a long time. Alex

hey sam does that 2 look more like an E? clean it up some more it might be an e for eaton

hey mike, if the axle tube was stamped "some were not for some reason" it will be located 6-12 inches from the center housing on the passenger side tube on the transmission side "front part of the axle tube. it will be hard to read with all the road grime but some brake clean and a scotch bright pab or a wire brush and it will be viewable. to tell if a posi is in the housing jack the car up and spin one tire if both go in the same direction then there is a posi unit installed. as for if it was factory and if it was stamped it will have one of these stamped on the tube with the code: D= Dana Positraction Differential E= Eaton Positraction Differential W= Warren Motive if it was not stamped at all you will have to open up the differential cover to see by looking for gm part numbers on the gears and unit Alex

if it is not stamped with a letter on the out side you will have to operate and open her up to find out by looking on the gears inside.

now sam if you would hae done your homework like i did you would have visited the tech info page to see what i wrote up a while back on this lol 1970 The 1970 Monte Carlo is a year that is unique to the first generation of Monte Carlo’s. It is the only year that Chevrolet had the three-digit rear axle ratio identifier “CCH for example all of them started with C for Chevrolet” and the only year that they had a month and day code “01 23 known as January twenty third” for the Monte Carlo.

Thank You Alex for taking the time to research, and write all of this out for us.

the 2 would be second shift alex

why not cover the threaded ends of the bolts with locktite or an anti seize compound using stainless self locking type bolts from ARP. that should eliminate/reduce the problem of electrolisis occuring. just a thought but someone else can chime in on this

the gasket should prevent that at i would think

year one has them as well as paddock see parts page for website info
