Front bump stops

[gs.davies]

I’m painting up my front subframe and I don’t recall taking bump stops off it.

Where I think bump stops would be is fitted an oval plate.

Is this right or should bumps be fitted?

The plate is part of the bump stop, but should have the cone shaped rubber bonded to it (not uncommon for them to part company and the plate be left bolted to the subframe).

Being oval, it will have two threaded studs that go through into the suspension tower with 7/16"AF nuts, It'll be a pig to remove if the suspension is built up! But must be done to ensure the top arm can't go too high, stressing the ball joint which could lead to the ball joint pin snapping.

Thanks, that’s good info. I’ll add some new bump

I'm puzzled here Graham and GS....., so much so that I've looked at the parts list and at my bog standard car. So far as the front bump stops are concerned, then surely, if I'm right, then the rubber buffer is bonded to a steel squared plate that straddles the top arm and is retained by a longitudinal nut and bolt. when the car/suspension is in bound, the buffer contacts the underside of the sub frame tower. That's all there is. The bump stop buffer is fitted to the top suspension arm that's why you don't remember taking it off the sub frame. Please feel to correct me

Yes Hydro cars have the bump stop attached to upper control arm. Dry cars the bump is attached to sub frame tower with two 1/4 fine studs on an oval plate. Later A+ bump stops have a round plate bump with a single 1/4 stud. Steve (CTR)

As described by Coopertune, my car being dry should have had them bolted by two bolts to the subframe facing the top arm.

I’ve owned the car since the early 90’s and they were missing from before then. The car was restored before I got it and the subframe was freshly painted then as I recall and so the remains of the backing plate, minus the rubber parts have been there ever since.

New ones ordered and as noted, they’d be a pig to fit with a trumpet and a top arm in place!

I have in my tool kit a cheap small 5 inch long 7/16 combo box / open wrench. I heated it center and bent it a little less than 90 degrees. I also wiz wheeled a 1/4 slot in the box end. I have found grinding the flat plate off the studs from under beats cussing the wrench and design trying to remove. Going back is not so bad with new hardware and the angle wrench. Steve (CTR)

Not original, but I convert to the later type - it is much easier to hold the nut and spin the bump stop!

[gs.davies]

That would have been a good idea if I hadn’t already ordered the two stud type.. why didn’t I think of that?!

Imagine being the guy on the line who got that job back int the day? What a crap design.
