gen1 toyota diff question

[to_easy]

what i need to know is the bolts that hold the diff centre in are they just a screw in stud sort or are they just a bolt that just get pulled in like a wheel stud.

Stud. A common trick is to replace the studs with set screws from the inside so that they cant come out..

Are the diff centres from a 1st gen Lux the same as a 2nd gen Lux??
Size wise, I mean, will a centre from a 1st gen fit into my 2nd gen??

the problem ive got this that one of the bolt or stud has broken on the bottom and is leakin diff oil and the bolt -stud is just sitting in there and i cant tell what it is a stud or a bolt sort.

Sometimes the hardcore guys weld up their drain plug and install a bolt into the bottom stud hole.. They remove the bottom bolt to drain the oil..

Anyway, its most likely a snapped stud. The only easy way to get it out would be to disassemble the axle and remove the centre to get proper access to the stud. I removed a heap of studs from a cruiser 9 inch axle.. They are loctited in there and I needed to get the oxy in there to release the loctite. You could try drilling the stud and using an extractor, but I dont think that would work.. If you did get it out you could just replace it with a bolt.

yeah it seams a lot of work for one stud and a little oil leak , i was thinking if i could just stop it from leakin some how but im not shore how i go about it , silicone it or some thing from the out side sounds to easy plus it probably wont work.

I have a crack in my alloy gearbox fill plug where the previous owner over tightened it and cracked the housing about 20mm and I have just cleaned it and covered it in silicone. This works until I need to change the oil then I just do it over again.
I reckon it's worth a try, at most it will cost a little bit of time and a few $$ for silicone.

Drill it and use an easyout to get the stud out and replace it with a bolt or another stud. It's not that hard.

at the moment im not really worried about it but i just want to stop it from leaking oil and later down the track ill fix it properly plus i just wanted to find out if it was a bolt or a stud so i new what i was in for.
