I was wondering if there is any way or alternative option to replace both of my driveshafts, for example from another vehicle which maybe has the same measurements?
The problem is that I'm still a student, I don't have a lot of money and my drive shafts are already pretty close to the end.
Is there any alternative or perhaps someone who sells drive shafts that are not too expensive but still in mint condition?

 

Not an ideal student car. I don't know of a straight swap, but how many km on the car, do you instead mean the inner tripod or outer CV is worn? If the axles themselves are in bad shape in the splines, a Mazda wrecker with a selection of rwd platforms would be the place to look to see if there's anything close.....maybe have to recut circlip grooves if you did have luck and then negate any savings.

One further point, not uncommon to see people over here selling used rear end parts. Through ignorance they don't realize they need to keep track of which side the axle came from - force reversals are less than great for them!

 

No guarantees but you might contact a member here…tomsn16. He does the occasional part-out , and is a trusted seller here. If he has used OEM their condition will be represented accurately and priced at fair market.
As for trying to get by on the cheap with something else….Price and cost…two different things.
edit: Not sure he ships internationally

 

What makes you think that your drive shafts aka axles are worn out? What are the symptoms?

Axles rarely wear out on stock-ish cars so you may be diagnosing incorrectly...


And, as other said, the FD is a terrible car for anyone w/o disposable income.

 

i have wondered the same … even with a heavily modified fd the stock axles are fine

 

So to put it simply, as soon as I put power on the rear axle (press the gas pedal) and turn the steering wheel slightly or hard, the car starts to wobble and "jump" extremely at low speed. I have to mention that 1. it will be less when the car and the rear axle have warmed up properly and 2. it can only be the drive shafts, because I already had the differential open and there were no chips and I replaced the old diff brackets with brand new powerflex ones.

 

Did you check your rear suspension bushings and pillow *****

 

I would suspect a Torsen gear issue (not too likely) or the wrong type of lube (or no lube) in the diff. It sounds like a "stick-slip" friction issue to me and the diff could cause it.

Worn suspension bushings, etc. would exacerbate this.

 

I checked those, yes they're fine.
I changed the differential oil recently and Im 100% sure i filled the right type of oil in the diff.
The diff looks like new without any scratches or damages

 

Got a video?

 

I'll do one during the day tomorrow.
One with the rear axle cold, and one when its all warmed up
