Trailing Arm Bushing Replacement

Join me on a journey tackling one of the T25’s notoriously difficult areas – the trailing arms. Sparks fly whilst I remove hub nuts, disconnect brake lines, snap bleed nipples and meet the tin worm.

If your bolts are seized like mine, I recommend using a power saw to cut them off. I used an angle grinder but struggled with reach and control in such a tight area.

When fitting new Powerflex set I use the GoWesty technique to fit the bushings with a 30cm M12 threaded rod, nuts and washers. The only difference is I use jubilee clips to compress the bushing, instead of an tapered pipe (or the specialist 3053 VW tool).

To calculate the 500Nm force for the hub nut I used the following formula to calculate where I should stand on the breaker bar:

Force x Distance = Torque
80kg (my weight) x 64cm = 502Nm

Useful resources and research:

As mentioned in the video, you could use T4 Trailing Arm Inner Bushings instead which are a split design so really easy to fit. They are the same part number (251501131A).
