Back End Sway

[MartinR]

Hi all. When I accelerate hard in my Stag (not often) and then take my foot of the accelerator to change gear I get a disturbing back end sway which soon corrects itself. I wonder if it is tyre walls (not sure how old the Tyres are), or suspension bushes. Being kind of new to actually driving a Stag not sure if this unusual, expected or what. Any advise would be appreciated.

This will be the famous Stag twitch!

have a look at the Monarch website, click suspension for a write-up on the subject.

Classic. What an answer, I don't feel so bad now!! I plan to change the shocks and tyres over the summer with any luck and I may move away from original speck to improve safety. Thanks for your help.

I had the same on mine. I overhauled the whole rear over the winter. Things to look at to cure the twitch are, greasing the splines in the half shafts. (CV grease) and changing the trailing arm bushes to Poly. It cured it totally on mine.

I fitted rilsan coated driveshafts - fixed the problem instantly.

I thought it was part of the fun of driving a stag

Replace your trailing arm bushes with poly ones, i was going to do this last week, but, the mother in law caught man flu so i had to go to Lanzarote with my wife and child instead:dude:

i'm also thinking of new shocks for the rear, do i go for standard, spax or Gaz??

Drilled my driveshaft splines to take grease nipples so I can pump them full of CV grease from time to time - cost less than a quid...

Hi MartinR, I don't think it's Stag twitch, not in a straight line, something similar happened to me, it turned out that one rear shocker hadbroken away from its bottom mountingbolt, an easy enough fix but very alarming. Martin.

Hi Martin R. Like Martin I don't think it is 'the twitch', when you are in a straight line and moving with lots of power. The suspension is trying to cope with the torque and something is not right.

Shocks or Dampers are meant to deal with this sway, as well as bumps and thumps and easily changed.

I would ask someone to check out the whole rear suspension, bushes, shocks, springs and tyres. Then you can decide whether you are going to keep your foot off the loud pedal or as Stag owners do, Pay up and know that you will (eventually) be happy.

Hope you have a good first season.

Hi Martin R

I go to ALdridge on a regular basis to see several customers in the area, if you want me to pop round and have a look at the rear suspension for you let me know and we will arrange a day and time.

I thought that this was about that Kirst woman whenI saw the title

I have completely new rear suspension and poly bushes and mine does this occasionally. Not that my opinion on any such matters counts for a lot but my money is on stickiness somewhere near the ends of the driveshafts

I often thought of doing this and as my rear (and front) suspension is out right now it would be time to do it. Do you think it would weaken the drive shaft or throw it out of balance and would you happen to have some photos.
