latches at maximum... what else?

Hi there,

Today I've put on my hardtop and the latches seemed loose, so I've tried to
adjust its tension by turning the hex bolts in them. I've found out that
they are already at its maximum, so there is no more thread available for
those adjusting hex bolts.

Can the Frankenstein bolts be adjusted rearwards or something? Any other
ideas?

I'm not even sure if new (and expensive!) latches would sort this out...

thanks!

Have you tried doing the adjustment in the opposite direction? I don't have
a clue but some times these things can be counter-intuitive. It's worth a
shot, right?

Don't forget that the latches them selves might be moveable. The ones on
the soft top have slotted screw holes, IIRC.

I'll have a look. Thank you!

The metal part of the hardtop that actually attaches to the
Frankenstein bolts is adjustable by about 3/4" forwards or backwards
on each side.  This is probably an adjustment everyone should
investigate.  To get to this, use a Philips head on the horizontal
screws (careful, they're short) on each of these metal panels.  Take
those screws out and the top half of the panel will swing around to
reveal the fun plastic bit that hooks on to the f-bolts.  Loosen the
bolts inside (8mm IIRC) and move the hook forward or back to adjust.
I also put some washers underneath that part (between it and the part
it mounts to), which raised it up, and helped me to further tighten
down the rear end of the hardtop.

You should make sure you're using the side latches as well.  They have
made the biggest difference out of all.

One last note:  my front latches are the loosest part of my hardtop
assembly process...but I don't doubt that my hardtop is as tight and
secure as it can be.  Make the judgment yourself.

Wow! I will investigate those bright mistery metal boxes ;) There seems to
be plenty of potential :)

Thank you very much. The facts are:

-It seems loose
-It makes noises over low speed bumps (specially on single wheel bumps,
where it sounds like if it was comlpetely loose!)
-At "high speed" driving (i mean over 140kph or so) you can feel aerodynamic
noises coming from the front top end.

I hope I am able to fix all this before good weather cames back!

I forgot to mention...for noisiness, check out where the hard top has
those tabs that hold down the soft top and keep it from rattling
around...the latches and these tabs rattle around with each other all
the time in mine, so I tuck the corners of the blanket I cover the
soft top with between these two metal bits.  This helps with noise at
slow speed!

Best,

mmm.... tabs? I'll have a closer look!

By the way, I've looked into those mistery boxes, and I've seen I have
something to experiment with during the weekend. I'll post a progress update
next week...

thanks!

I have tried to tighten the hard top by moving those u-shape things which
match the frankenstein-bolts, but the nosies are still there. The front
latches are still un-tigth, and no further adjustment is possible.

I will try to move the position of the latches on the top, by making a
little slot on the bolt holes if necesary, to see if this will help.

I've seen the tabs you mentioned to hold the soft-top in place while the
hard top is on. They are fine, and the problem doesn't seem to come from
there...

Thank you and regards.

At this point I'd try having a friend survey the source of the noise
from the passenger seat while you drive...this is a great way to track
down rattles.

Also, try putting on the latches in a different order...if you were
doing the side latches first, do the front first, or visa versa.
