ezzzzzzz Posted April 20, 2005 Share Posted April 20, 2005 I have a chance to pick up some axles kinda cheap ($50 a pair) from a 84 300ZX turbo but I have to pull them. Before I make the trek to the source I'd like to know if these are the axles I want. I'm looking for the Z31(?) CV axles in the 4 bolt pattern. Are these it or are they the earlier 6 bolt pattern? Thanks for any help! Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted April 20, 2005 Share Posted April 20, 2005 The 88 turbo shafts have the 4 bolt pattern. I'd say that the 84 does also.... Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted April 20, 2005 Author Share Posted April 20, 2005 While doing some quik searching I came across this bit of info... "There are only two differential companion flanges. The 84-86 models have a slightly offset bolt pattern (i.e. make a rectangle). The 87-89 models have a equal bolt pattern (i.e. make a square)." Does this imply that the earlier 4 bolt pattern (at the axle stub flange) is rectangular and the later is square? I ask because I want to use Ross' billet companion flanges which appear to be square. I don't want to waste time or money on parts I can't use. Quote Link to comment Share on other sites More sharing options...

When I ordered a pair for my swap, the part numbers for the reman. units i got were all the same for 84' to 89' turbos. Quote Link to comment Share on other sites More sharing options...
RedZ85 Posted April 20, 2005 Share Posted April 20, 2005 I have never heard of 2 different turbo companion flange patterns. Quote Link to comment Share on other sites More sharing options...

I did not know they were different at the wheel end also. We all know about the diff end stubs being special for that unit only... Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted April 21, 2005 Author Share Posted April 21, 2005 I got my axles ($52.50) this morning. These are the 4 bolt type. It took about 45 minutes to pull them with hand tools. Luckily, the car was off the ground on welded rims for easier access. The axles are in good shape aside from a little dirt and rust. The last steps are purchasing the billet Z31 companion flanges from Ross, having the custom axles machined, assembly of the axles and tearing the rearend apart for struts, springs, mustache bar, bushings, etc. That should take about 15 minutes...LMAO!

Drax240z Posted April 21, 2005 Share Posted April 21, 2005 I've got a set of 85 turbo ones that are 6 bolt pattern. Quote Link to comment Share on other sites More sharing options...
wheelman Posted April 22, 2005 Share Posted April 22, 2005 Drax, Those aren't from a turbo, they all had 4 bolt setups and the N/A models had 6 bolts. Go figure. Wheelman Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted April 22, 2005 Share Posted April 22, 2005 Can anyone tell me which model Z came with the inboard flanges on the axles, that have 5 bolts ? The inboard stubs that plug into the diff have 5 bolts and seperate from the axles at the wheel side, and the diff side.... They are kinda a 5 point star shape.

Drax240z Posted April 22, 2005 Share Posted April 22, 2005 Well I pulled them off a turbo car myself. However with that said it's entirely possible that a) canadian model is different (I know for sure other parts are different on canadian model 300zx) or the car had a non-turbo rear end/axle swap, as it was made from a pair of cars.

wheelman Posted April 22, 2005 Share Posted April 22, 2005 Could be different in Canada, everything else is. JK I'm sure the turbo cars in the states all have 4 bolt patterns I researched it before doing the conversion on mine. If the car was a combination of 2 then anything could have been swapped so who knows. Wheelman Quote Link to comment Share on other sites More sharing options...
Guest zfan Posted April 24, 2005 Share Posted April 24, 2005 When I pulled my 3.70 LSD off of a 1987 300ZX Turbo I too the cv's as well. The cv axles have 4 bolt flanges on them. I just went out and checked after reading this post. Mike Quote Link to comment Share on other sites More sharing options...
