Cutting Shock Bolts

I've been told that the bolts holding my shocks in place will have to be cut in order to replace the factory shocks. This is from two places who have not seen the motorhome. I looked under it and saw no signs of rust or dirt on any of the bolts holding the shocks. I also sprayed a penetrating oil on all of them.

Is it normal for the bolts to be cut off? Anyone ever had this happen?

My MH is a National Tradewinds DP 2001 on a freightliner chassis. The Blistins were installed when she was new.

Thanks for all the responses and suggestions.

I took her in this morning to a highly recommended shop. He checked the alignment and made some adjustments and also checked the shocks. I was surprised he said the shocks are still good and he said it handled really good on his test run. On the way home it was like driving a different MH. Totally honest shop, hard to find these days. If you are ever in the Saint George, Utah area and need a good shop let me know.

It all depends on the mounting of the shock and what new hardware comes with the shock. if its just nut and bolt at one end , tighten them till it breaks off, if the lowers is a stud type, nut splitters work good or for the single threaded tops, if you have room to work. other wise the blue wrench or die grinder, it not like your trying to save the shock...

With me, my Harbor Freight impact gun and 125# air compressor were simply not up to the job. Borrowed a Snap-On impact gun and a 200# air compressor and that ALMOST took all those bolts/nuts off. The one that would really not budge, my (air powered) grinding wheel took care of it.

Also, in my case, the bolts and matching nuts were hardened...the nuts went on by hand only 2-3 turns...then the impact gun was needed do run the nut all the way to tight. (Got the hardened nuts and bolts from Grainger)

Yeah it's cheaper, but for who? The mechanic, the shop, the vehicle owner?

I've personally seen "mechanics" who are quick to get out the cutting/welding torch and get to work. In their haste to git 'er dun, they fail to look for, or, cant read the placard that says words to the effect of: CAUTION HEAT TREATED DO NOT CUT OR WELD FRAME MEMBERS OR SUSPENSION COMPONENTS

When the parts they were "working/cutting/welding on" fail prematurely, they're long gone with all YOUR money which THEY saved. You, if you are still alive, get to deal with the aftermath.

I'm not opposed to getting aggressive to "git 'er done." Just be sure YOU know what you're doing first.

On many motorhomes, depending on one's girth and agility and so forth, it may well be unnecessary to jack the unit up at all. It can't fall off the ground.


Most DIesel Pushers I have seen with air out of bags sit really low to the ground.
JIm was a member here and irv2 he was just about to leave out of his driveway for a trip and crawled under real quick to check something out and that was it.

I wouldn't cut them unless necessary. Ass someone else said some are part of the mounts.
This is why I like to paint the undercarriage. primer/paint in spray cans doesn't cost much. I can't think of brands but several coatings that turn rust into something won't corrode any more.

Often the bolt is seized in the metal sleeve that goes through the shock bushing. Getting the nut off is only half the battle. If the nut comes off easily, you may be in luck. If it needs a major dose of penetrating oil, the bushing is likely in even worse condition. I can understand why a shop would advise they will probably have to cut it off.

Well Sir,
I answered you in your other forum but, here it is. First, don't be so quick to butcher off ANY bolts until you put a couple of wrenches and or an impact on them. Unless you're doing this for a living and, you're working at a flat rate, you're not in a hurry. So, an attempt or two at loosening the bolts in question may reveal they're not on all that hard. Or, it may reveal they're rusted solid. But, you won't know 'till you give it the ole' College try.

Second, SOME folks cut them off because the bone heads in assembly some how set them up so they cannot come out due to insufficient clearance for them to be COMPLETELY removed. Now, you say you've looked under the coach to see them and, you've sprayed a bit of penetrant on them, correct? If so, do look under it again to see if there is sufficient clearance for complete removal.

If there isn't, then yes, it might be necessary for them to be cut. But, to just crawl under there with torch/saber saw/sawzall, whatever the cutting utensil is, and start cutting, without first attempting to remove them in a regular manor, well, that's up to you. It's much like seeing a door kicked in BEFORE trying to turn the door knob to see if it's unlocked.

Typically it's just a rather ordinary machine bolt and a nut, running through a bracket welded to the frame and the eye of the shock absorber (and bushings and washers and so forth). The bolt and nut are not welded to the frame. That, of course, is assuming the shock doesn't have a threaded stud sticking out the top that gets attached to a mount with a nut and bushing and washer at the top, such as is common on cars and/or some front suspensions.

I'm sure there are other variations on some vehicles, but these are the two general types of mounts that I've come across.
