Rear end shake BRZ - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

In my BRZ , When starting from stopped or slow speed’s turning left or right sharply, the rear end will judder/shake a little bit until I straighten it out, or pick up a little speed only shakes for a second. Could this be the rear LSD? Is it normal? It is an automatic.

It could be a lot of things, but it's a quick check to drain the fluid from the diff ( if there is any) and fill it with some new goop. Couldn't hurt to check!

Other things -

Check yo lug nuts boi
Check you axles and make sure the boots aren't torn and leaking fluid
Are you sure it's the rear?
See if your swaybar endlinks are attached properly
Check your strut mount bolts

Well it has done it for the entire lifespan even brand new

I do remember a bit of shudder when it was new, and maybe still does it a bit accelerating out of close turns. However, I'd recommend changing diff oil as mine got a bit better when that was done. I think it's normal behavior for the LSD.

My thoughts is it is the diff working, since you said it happened since new.

Otherwise if you are running with traction on it is very intrusive especially if you are adding throttle in a turn. The brake actuation may sound like a judder.

Doesn't sound like anything is wrong from your description.
