Same with 8859 (tractor - the worst technic set ever for power
transmission[1]), in red. On the new kind, though, the round recess
in the fingers get their edges bent out when the mating round raised
is slid past when disassembling. The same thing happens, slightly
less so, with the 4-wide hinged roof hinges.
On my Crisis News Cre set, the van's rear hatch comes out of the
hinges after opening/closing several times. I got replacement
pieces from Customer Affairs; same problem.

[1] It has the old style differential, with the old-style soup-cracker-tough
z14 bevel gear[2]. From the differential, 1 each of those gets
power to the piston engine (via about 10 small gears up a beam - horrid)
and to the farming attachments. Does not work well at all.
[2] I found a great new use for these - at 1.5 studs center distance
(or the equivalent 1-stud-over, 1-brick-up),
they mesh well with the replacement z12 bevel gear,
particularly if you use 2 z14s back-to-back and 2 z12s fac-to-face.
Ratio is 6:7, of course. Very useful for a very compact 8880 (SuperCar)
transmission; 7/6 is very close to SQRT(3), so 7/6 on the input
and 3/1 on teh output axles results in ratios of (roughly)
1, SQRT(3), 3, 3*SQRT(3). Very nice ratios, and very compact, particularly
combined with the V8 moved to the front and FWD only (will Consumer
Affairs sell me 4 more 8880 wheels, so I can have 2 FWD cars?).
