HELP Problem with the Ro

[gsd2000]

I need help. I have just come home from dropping my younger brother off at the cinemas and as i was parking up, i was reversing on the drive to align the car up and then the car locked.

I was reserving and then the back end of the car just stopped and i couldn't reverse any more, it was like the handbrake had been applied, i rolled the car forward about half a meter and reversed and got further back and then it did it again.

I managed to park up straight on the drive and got my trusty costco jack out and had a look underneath but i can't see anything out of place, broken or twisted. The diff has occasionally been knocking and making a few noises when changing gear and whinning a touch at times, mainly when i lift off in fifth and sixth but i was told that i would hear more whines and knocks as i have a fully polybushed rear end with the extra "hardcore" shims fitted, along with pedders XA coilovers.

I did try to reverse off the drive to check after i had inspected it to see if it was a one off but it did it again, i can reverse but i have to roll the car forward and then backwards over and over again to make progress.

I personally think that the diff is playing up but i need some other ideas of how to fully diagnose the car.

If the diff is on its way out and locking up then i wont be able to make thunder road

I recently bought some diff and gearbox oil and i was planning on changing them both before thunder road.

Or could it be the brakes binding?

As i did wash the car today and i have AP's?

please someone help

thankyou

first thing i would check would be the handbrake shoes as if a set has come adrift then it could be causeing it. Failing that could be the diff but i would expect it to be very noisey

the diff is a bit clunky when i try to pull away, but like i said i was told that it sounds clunkyer with the extra bushes, doesnt clunk once moving just sometimes when pulling away slowly

[neiljohnson]

Get it jacked up and have a feel if its the diff it should do it from both sides and iirc you can take the rear diff cover off and have a look inside. If its the handbrake will most likely only be the one side

I dont think it's the diff, but I have a spare you can borrow. I think Neils right and its the hand brake shoes.

[gsd2000]

Thats good to know, i dont think i will go to the breakfast club meet tomorrow and check the brakes instead.

My first thought was handbrake shoes. I don't know about the Monaro, but the VXR8 is very harsh - either on, or off.

Thanks for the help everyone there is hope thats its just the handbrak shoes sticking but why are they sticking in reverse only?

I know the handbrake setup on a ro is considered "unique", is there anything in particular "unique" about the handbrake setup?

The diff looks clean, no oil spray like the leak i had last time.

It a leading edge shoe design, so the front engages first, and very aggresively, thats why they are shite when going backwards. If they were "misaligned" I suppose you could expect that same fierce grip backwards aswell? Hope you can sort it quick mate.

It would be quite easy to drop the back discs off and have a look.

If a spring has dropped off?

Thats my thought , if a rear spring has dropped off or broken then the trailing edge of the shoe (going forwards) will have dropped and would bind up when moving backward.

That is exactly what i was after. Thankyou very much

[gsd2000]

Thankyou MYM8V8 and L2VXR for helping me out with the brakes, letting me borrow the lift and the cup of tea

odd how nothing is was wrong but looks like something has been there in the past.

I did find it odd how with the handbrake on the drivers side wheel spun when removing the wheel but once we had the disc off, inspected it and refitted everything the handbrake seemed to hold the wheel okay whilst tightening the wheel nuts up

[neiljohnson]

Glad you got it sorted see you at tr

[gsd2000]

Everything looks good enough for thunder road but i think that they will need adjusting
