Good shop in denver colorado area

[BIG C]

Hello, I am in need of A tractor repair shop for my Kubota L3830.
live in the Conifer/ Evergreen Colorado area( west of Denver)
the tractor is exhibiting a fairly regular and pop, bang or clunk from the rear.I think its in the left axle.
Can anyone recommend a shop other than UNIVERSAL TRACTOR?

thanks in advance.

Have you checked the lug nuts on the rear wheels? Loose wheels make all those noises and a few others. I hope that's all it is.

THANKS,
I did check all lug nuts and every fastener I could get a wrench or socket on.
all are tight. sadly.

Does it have separate axle hubs? If so, are they loose?

Im almost embarrassed to admit it, but i found the problem.
It has 2 part wheels, being the rim and center section(hub). All the bolts are tight, but the left wheels center section is cracked. It can only be seen from the back and at the right angle.
