Rear suspension nut sizes

Post by **southerly95** » Tue Sep 15, 2009 6:25 pm

Could someone remind what size nuts for the rear suspension:
- shackle bolts, and
- front locating pins

Many thanks, John

They 'should' be AF sizes (7/16 1/2 9/16 maybe 5/8, can't remember! ) - but over the years some replacement parts have been coming out with metric threads (and ∴ nuts) - so don't be too surprised!

Keep a 1/4 - 5/16 Whit spanner and sockets handy just in case.

Certainly the prop shaft bolts are 1/4 Whit!

Well bit of a mixed picture as expected. Items as supplied from DSN were front locating pin 3/8 UNF taking a 9/16 AF spanner. Rear shackle pins were 3/8 BSF taking a 5/16 Whitworth spanner.

Front locating plates had welded themselves to the shackle as usual although I was able to open the 'letterbox' slightly at the front end on both sides to get a spanner in to the boxed in nut (1/4 thread with 7/16 AF head).

For the first time I used Denso tape on the new springs as the car is used daily, having sprayed white grease in between the spring leaves. Think I will do that on our other two when I get the time. One 50mm/10m reel was just enough for both sides. Regards, John
