I pulled both my axles to replace the diff shaft seals on my transmission a couple of weeks ago and have noticed my diff is now making a loud clicking noise if I rock the car back and forth. Is this normal? I'm not sure if I'm just being paranoid and it was there before I did the work.

There is play in the shaft, with the back wheels off the ground I can rotate the wheel a little either way before the diff engages. The video below is the car parked and me just rocking it back and forth. I torqued the trans flange bolt to 19ft/lbs.

Believe it or not Tangerine Racing's have a machined lip:

Type 1 CVs

These are the only ones I found that do. Chris must machine them or pay to have them done. Well worth the extra $20 or so to get the stock gasket to fit. Been researching CVs since I'm getting pretty good at breaking the old ones.

I agree with Curt, neither of the scenarios you describe sounds good. You don't want it welded on, and you don't want it to slip off with no circlip either. It will just slip out eventually.

BTW I got my new CVs and the difference between a new CV and an old rattly one is pretty surprising. The new one feels solid, very little movement, ready to work. The old one felt easy to move in and out, much more loose.

Ugh, thanks Curt/Chris, obviously not what i wanted to hear, but good to know. What is the life expectancy of a cv joint? I ax the car once a month and drive it daily - my commute's only about a 5 mile round trip though.

I'd be more concerned about your life expectancy with the way you describe the set up that was put together.

Pull both your axles and assemble the CV's per spec. and stay off the freeway until then.
