Rear differential problem

Recommended Posts

Hi, I'm new to Foresters and have a problem with the rear differential on mine which is a 99 manual 2.0 litre GLS. The previous owner, for some reason, put an Impreza sti limited slip diff in the rear. This is very noisy now so I bought what was supposed to be a secondhand  4.111 manual diff and the garage says it wont fit because the splines are different. Are the drive shaft splines different on an Impreza?

 

thanks

 

Dave

I think you'd have to change the shafts to accomodate the different diff. So if you are reverting to standard i presume you need to change the driveshafts back.

There are a load being broken on eBay so you should be able to pick a pair up fairly cheap.

I'd sell the sti diff and shafts to recover some costs

Would of thought the GLS was mechanical LSD as standard (all S models are but 99 year could be either), Splines are longer on the LSD I believe.

Personally I would get another LSD diff over going standard open diff ...
