rear end question

[Bing]

So i just bought a disc rear end today

I check the posi by holding one end and trying to turn the other, and it's real tight

however after i got home, i found out that both axles have a in/out play of about 4-5mms

is that normal at all? if not is there anything I can do to fix this?

I actually had the same thing on my last rear end too, but only about 2-3mm of play.

[Bing]

btw this is a 9bolt rear, so no c-clips

could it be the axle bolts(whatever they are called) are loose? I know the guy had everything apart, so don't know if he actually tighten them and such

4-5mm is a fair bit,

the bearings are pressed on and held by a retainer plate,

the backing plate is the retainer, check the 4 bolts see if they are loose,

if not either the axles are pulling out of the bearing, or something is worn,

I wouldn't be terribly worried about it, but keep an eye on it

Thanks man, I kinda suspected you were the one I should ask about these rear ends lol.

are the 4 bolts the ones I can see when I open the cover? sorry I know next to nothing about diffs.

the retainer plates are on the housing ends

i'm a retard when it comes it this jason lol

I know the diff housing is the big thing inside the middle part of a rear end with the big gear on it lol, that's pretty much yet; so retainer plates are at the 2 sides of the housing? like where the axle shafts connect to the housing?

ends, as in where you bolt the wheels to the axle, the tube ends

[Bing]

lol ok i know what you mean now, it is loosened haha

I thought those 4 bolts are just for the caliper brackets

its also the bearing retainer,

just becareful if you start fucking with it

the seal and you'll be in for a headache

[Bing]

hm... so what should i watch out for when i'm tightening them back up?

[89vert]

if the bolts are lose just tighten them,
if you start pulling the axle out then you could run into problems

Cool thanks
