Question about 1984 Chevrolet Camaro
I got an 84 camaro that has 410 gears, trying to go back to stock 373s. How hard is this to do? I do have a bit of experince with auto work, but never done anything with the rear diff other then removing axles to fix axle seals. When I asked a local ase certifed mechanic he was talking about spacers and everything. What is the PROPER proceedure to do this task? Other then the obvious that is. Thank you.
Sorry, for not getting to you sooner. What the mechanic is saying is correct. Their are many measurements required to do this correctly. The pinion has to have the correct height adjustment so it rides even with the ring gear. This adjustment I get from running a depth mic ftom a homemade straigh edge that I blanchard ground and bolted up to the bearing cap. If you are not close or correct the first time you have to have a hydrolic press to push the bearing off and re-shim. Once you have got this taken care of you have to set you side clearence. This is where you have to take the total distance and start splitting the sides removing.... lets say .020 on one side and adding .020 to the other side. It gets to where you are dealing with .002 at a time towards the finish. You keep working this shim combo until you have a good track on your gears. I am very mechanical and did not learn this until I went to work for a machine shop (learning measurments and tooling) once I had the knowledge there I applied it to a friends race car and here we are in its second season. My suggestion would be to just R&R the rear end if you can find one. Time and tooling will just eat you up if it is just a one time deal. If you still feel you want to try I will do everything I can to walk you through it. Youtube can be a source that I can upload info too. I will be doing my daughter 1977 formula firebird in about a month. She needs 342 gearing and posi trac. I hope this has not come to late..... Check my sons camaro out on youtube it is not painted yet but the mechanical part is good. It has a 350 small block with a 4 speed T-10 and 373 positrac. It is under (1978 camaro driveway burnout).
